My gum disease has advanced: will I lose my teeth?

At which stage treatment stops it, and at which stage a tooth can no longer hold on

If your gums are bleeding or have receded, or your teeth have started to move, the real question is what stage the disease is at. On this page we explain the difference between gingivitis and periodontitis, how pocket depth and bone loss shape the decision, and the point beyond which a tooth has nothing left to hold on to. Send us your X-ray and we will write to you within 24 hours to tell you what stage you are at.

Short answer

It does not mean you will lose all of them. Gum disease progresses in two stages: gingivitis, which affects only the gum, can be reversed, while periodontitis, which destroys the tissue attaching the tooth to the bone, can be stopped, but bone that has been lost is not put back. Two measurements decide which teeth will stay: the depth of the gum pocket and how much of the bone around the root is left. If most of the root is still inside the bone, the tooth stays in place with treatment. If the bone has been lost down to the tip of the root and the tooth is loose, there is nothing left for it to hold on to.

Where gingivitis ends and periodontitis begins

Gum disease is not a single condition but two stages, one following the other. The first is gingivitis: the soft layer of bacteria that builds up on the tooth surface (plaque) irritates the gum; the gum turns red, swells and bleeds when you brush. At this stage the bone holding the tooth in place has not yet been affected, and once the plaque is removed regularly, the gum returns to how it was. Gingivitis is the only stage that can be reversed.

The second is periodontitis: the inflammation goes down below the gum, into the fibres attaching the tooth to the bone and into the bone itself. Tissue that has been lost does not come back; treatment stops the disease progressing but does not put back bone that has been lost. That is why the answer to 'will I lose my tooth?' depends not on how bad your pain is but on how much of your bone is left. Periodontitis progresses without pain; many people first notice the disease when a tooth becomes loose.

There is a natural, shallow groove between the gum and the tooth. At the examination, a fine probe marked in millimetres is placed into this groove; the measurement taken is called the pocket depth. In a healthy mouth it is no more than 3 millimetres, which means a toothbrush and floss can reach it. As bone is lost, the groove gets deeper; beyond 4 millimetres, no cleaning you do at home can reach the bottom of the pocket, and the bacteria stay sheltered there.

The second measurement shows on an X-ray: how much of the length of the root is still surrounded by bone? If the loss is confined to the upper part of the root, there is still a foundation under the tooth to carry it; if the loss has reached the tip of the root, there is nowhere left for the tooth to hold on to. Dentists combine these two measurements with how many teeth the disease has spread to and grade the condition in stages from 1 to 4. The stage number is a description of how much tissue has been lost for good. That is why the question 'will I lose my teeth?' is not answered with 'all of them' or 'none of them': in most mouths, some teeth can stay and some cannot.

Which teeth can stay and which cannot

This distinction becomes clear after an examination, pocket measurements and an X-ray. Seeing yourself in the second list does not mean you will lose all your teeth; most mouths have teeth from both lists.

The tooth can be saved

Bleeding, but the bone is intactIf the bone level on the X-ray is normal, the condition is gingivitis. With a professional clean and an improved routine at home, the gum recovers within a few weeks; tooth loss is not something that needs discussing here.
Pockets of moderate depthIf the pocket depth is in the 4–5 millimetre range, root surface debridement (deep cleaning) below the gum is enough: the pocket gets shallower, the bleeding eases and the bone loss slows down.
Bone loss confined to the upper part of the rootIf most of the root is still inside the bone, the tooth goes on carrying the load of chewing. Keeping these teeth in place is our first aim.
The tooth does not move when you push itA tooth that does not move is the most practical sign that the bone is still doing its job. Even if it has a deep pocket, we try to keep a tooth that stays firm in place with treatment.

Saving it is unlikely to hold

The tooth shifts when you biteWhen looseness goes together with advanced bone loss on the X-ray, most of the support has been lost. Early-stage looseness caused by inflammation or by the load of chewing eases with treatment; holding on to a tooth whose bone has gone, on the other hand, costs the neighbouring teeth their bone too.
Bone loss has reached the tip of the rootIf the root sits almost entirely outside the bone on the X-ray, there is no pocket that cleaning will close. What we will talk about is not saving the tooth but preserving the remaining bone.
You are still smokingSmoking reduces the blood supply to the gum and weakens the response to treatment. If you are not thinking of stopping, let us talk about it at the outset; the plan and what you can expect both change accordingly.
Your blood sugar is not under controlIn uncontrolled diabetes, gum inflammation takes a more severe course and wounds are slow to heal. We ask you first to get your blood sugar in order with the doctor who manages your diabetes: diabetes itself is not an obstacle, but uncontrolled diabetes is.

How we find out what stage you are at

This sequence is for diagnosis, not treatment. At the end of it you will know which teeth can stay, which cannot, and why.

1
Send us your X-ray
If you have a panoramic X-ray or a CBCT scan, send it through the form. Our dentist reviews the image, and we write to you within 24 hours to tell you what stage you are at. You do not need to come in for this step.
2
Pocket measurement
Measurements are taken at six separate points around each tooth; the probe is fine and blunt, and the measuring takes a few minutes. The result is a map of your mouth; without this map, neither the staging nor a treatment plan can be put together.
3
Recording bleeding and looseness
Points that bleed during the measurement are where the inflammation is active. How loose each tooth is gets graded separately; looseness is not interpreted on its own but assessed together with the bone level on the X-ray.
4
Bone level on the X-ray
A panoramic X-ray gives the overall picture. If implants are going to be discussed, we ask for a three-dimensional CBCT scan: it shows not only the height of the bone but also the thickness of the hard layer on the outer surface of the jaw (cortical bone). The decision on strategic implants is made by looking at this layer.
5
We talk about smoking, diabetes and your medicines
How many cigarettes you smoke a day, your HbA1c, which shows your average blood sugar over the last three months, and the medicines you take all directly affect the plan; a plan put together without them is incomplete.
6
We go through the plan together
We explain clearly which teeth can stay, which cannot and the order of the procedures. If there are teeth that will be kept for now and looked at again in a few months, we tell you that too; not every tooth falls neatly into one of two groups from the start.

The routes open to you

Which one is right depends on the stage. The list starts with the least invasive, and in most mouths several are used together.

Deep cleaning below the gum

Tartar and plaque are cleaned off the root surface below the gum; in gingivitis and in early to moderate periodontitis, this is the first step. The pocket gets shallower and the bleeding eases. It does not bring back bone that has been lost; its job is to stop the disease progressing.

Gum surgery

In deep pockets that do not close, the gum is lifted back to reach the root surface directly. In narrow hollows in the bone, we regain part of what has been lost; the shape of the hollow decides it.

Extracting teeth that cannot hold on and replacing them with implants

When teeth that cannot stay are taken out, the source of inflammation in the mouth goes too. The strategic implant we use locks mechanically into the hard layer of bone on the outer surface of the jaw (cortical bone); a conventional implant anchors in the softer, spongy bone inside, and you have to wait for it to fuse. Because that spongy bone is the tissue periodontitis destroys most, in many mouths where the conventional route would need a graft and months of waiting, we move to final fixed teeth in three clinical days. The protocol is for the full mouth or many missing teeth; when a single tooth is lost, our approach is different.

Monitoring

In gingivitis, monitoring for a few weeks to see whether the gum recovers once your care at home has changed is reasonable. In advanced periodontitis, monitoring is not a decision but putting the decision off.

What you need to know when deciding

We write about these so that you can ask the right questions whichever dentist you see. If a dentist does not bring them up, ask.

Bone that has been lost does not come back on its own

Gum treatment stops the disease; it does not put back bone that has been lost. As long as the loss continues, the options for the next plan narrow too: a mouth that could be dealt with today without additional surgery needs a more extensive plan later.

Untreated gum disease carries over to implants too

An implant cannot decay, but the gum and bone around it can become inflamed with the same bacteria (peri-implantitis). An implant placed before the disease is brought under control repeats the same problem on a new surface; an implant does not replace gum treatment, it waits its turn.

Smoking also suppresses the warning signs

Because smoking reduces the blood supply to the gum, early warnings such as bleeding become weaker, the disease progresses more silently and healing slows down. Stopping does not replace any of the procedures here, but it raises what you can expect from all of them.

Uncontrolled diabetes works both ways

When blood sugar is unstable, gum inflammation takes a more severe course; ongoing inflammation in turn makes blood sugar harder to keep stable. Diabetes that is under control is not an obstacle, and we use the protocol for our patients with diabetes; when it is uncontrolled, though, it is something that has to be dealt with first.

Having no pain is not good news

Periodontitis progresses without pain; when the first sign noticed is a loose tooth, part of the bone has already gone. It is better to watch for bleeding, receding gums and persistent bad breath than for pain.

What to expect after treatment

The sequence below applies when gum treatment is chosen. When extraction and implants are on the table, the process runs differently; we set that out separately in your plan.

The first few days
Sensitivity to cold after the cleaning is normal. Because the swelling goes down, your teeth may look a little longer; this shows that the inflammation has eased, not that your gums have receded further.
The first week
The bleeding eases noticeably. We ask you to make using interdental brushes or floss a habit this week: between two check-ups, you are the one doing the cleaning.
Measuring again after six to eight weeks
The pocket depths are measured again from scratch and compared with the first map; a separate step is planned for areas that have not got shallower. It is to be expected that not every pocket closes in the first round.
The maintenance interval
In a mouth that has had periodontitis, check-ups are not once a year but every three to four months. Keeping to this interval after the disease has stopped protects what has been gained.

Message us right away if

Your gum has started to swell and throb. Inflammation building up in a deep pocket may have turned into an abscess. Call us without waiting.
A tooth has quickly become noticeably loose. Looseness that changes quickly needs to be assessed; we may need to bring your appointment forward.
You have a fever. A fever can be a sign that the infection has not stayed confined to the area. Call us without waiting. If the fever comes with swelling spreading into your face or neck, or difficulty swallowing or breathing, do not wait for us: go to the nearest A&E wherever you are.

What decides the cost

We do not give a figure on this page, because the right figure can only be given once the pocket measurements and X-ray have been seen; the difference between cleaning for gingivitis and treatment for advanced periodontitis is very large. Send us your X-ray and we will share the scope and the amount in writing. These are the items that decide the price:

What stage you are at: Cleaning for gingivitis, treatment below the gum at the moderate stage, and the surgery or implant plan that comes up at the advanced stage are different jobs. The difference between them can be several times over.
How many areas need treatment: Whether the disease is concentrated in a few teeth or has spread to the whole mouth. This directly decides the number of sessions and the total time.
Whether a tooth is kept or replaced: Treating a tooth that can be saved, and extraction with implants, are separate items. In most mouths both are involved, and the plan is put together accordingly.
Whether additional surgery is needed: If a procedure to regain bone in hollows inside the bone is needed, or a graft on the conventional implant route, the scope widens. With strategic implants this item does not come into it in most mouths; the CBCT scan decides.

Frequently asked questions

My gums bleed when I brush but I have no pain. Is it serious?

Bleeding is the earliest sign that inflammation is active; having no pain does not make the condition any milder. Underneath the bleeding there may be only gingivitis, or there may be bone loss. What tells them apart is pocket measurement and an X-ray; do not rely on a guess about the stage made without them.

My gums have receded and I have lost bone. Will it come back?

Bone that has been lost does not come back on its own; the job of treatment is to stop the loss and preserve what is left. In narrow hollows that have formed in the bone, we regain part of the loss with a surgical procedure; with bone loss that is widespread and even, no such gain is possible.

I do not want my loose tooth taken out. What happens if I wait?

Not all looseness is the same. Early-stage looseness caused by inflammation or by too much load when chewing eases after gum treatment; we keep the tooth in place by bonding it to its neighbours (splinting). With a tooth that shows advanced bone loss on the X-ray, the picture is different: waiting there does not save the tooth, it wears away the remaining bone too, and an area that could have an implant placed straight after extraction today needs a more extensive plan months later. Pocket measurement and an X-ray tell you which of these applies to you. The decision is still yours; in the second case, make it knowing that waiting is not free.

Can I have implants while I have gum disease?

We do not plan implants until the disease is under control. Diseased teeth and deep pockets left in the mouth act as a reservoir for bacteria, and the tissue around an implant can become inflamed with the same bacteria. That is why removing the teeth that cannot be saved and getting your care at home established come before the implant. When the order is right, having had advanced gum disease is not an obstacle.

I smoke. Will you not treat me?

We will treat you, but we talk about expectations at the outset. Smoking reduces the blood supply to the gum; the course of the disease, the response to treatment and healing after procedures are all affected by it. We ask you to stop, or at least to take a break for the healing period. We say this not as moral advice but as part of the plan: if you carry on smoking, the list of teeth we can keep changes too.

I have diabetes. Are implants possible for me?

If your blood sugar is under control, yes; we use the protocol for our patients with diabetes. What matters is not the diagnosis itself but how well it has been controlled recently. If it has been unstable, we ask you first to get it in order with the doctor who manages your diabetes: in uncontrolled diabetes, wounds are slow to heal. This is not a refusal but a question of order.

If I am going to lose most of my teeth, do I have to wear a full denture?

No, that is not the only option. The protocol we use for the full mouth or many missing teeth is teeth fixed onto implants. Because the strategic implant locks into the hard layer of bone on the outer surface of the jaw, it does not depend on the spongy bone that periodontitis destroys most; in most mouths, patients leave with final fixed teeth after three clinical days. The CBCT scan decides.
