Tooth Movement & Loss

Food getting stuck between teeth

If it gets stuck in the same place at every meal, that is not a habit but a sign

Poking at the same spot after every meal, reaching for a toothpick several times a day and that feeling of pressure in the area: most people think this is just a fact of life. It is not. Food getting stuck in the same place every time tells you that the contact between two teeth has opened, and that opening has a cause. On this page we have written about the causes, what food trapping does to the gums and why a toothpick is not the answer.

Short answer

Two healthy neighbouring teeth touch each other at a tight point, and this contact stops food getting in between them. When the contact opens, food gets stuck in the same place with every mouthful. The most common causes are these: teeth tipping and drifting after a neighbouring tooth has been lost, a worn or broken filling, decay starting at the contact point, a badly fitting crown and receding gums. As long as the trapped food stays there, the gum becomes inflamed and the pocket deepens.

What it means: The tight contact between two teeth has opened
The most common cause: Drifting after tooth loss, a failing filling, decay
The result: Gum inflammation, a deepening pocket, decay, bad breath
Toothpicks: Not the answer; they make the gum recede

Why it always gets stuck in the same place

Two teeth standing side by side do not touch along a flat surface but at a small, tight point. This point is one of the least noticed but most useful structures in the mouth: during chewing it acts as a lid against the force pushing food upwards. If the contact is tight, the mouthful cannot pass through; the moment it loosens, food is pushed a little further in with every chew.

The most common reason this contact opens is the loss of a nearby tooth. When a tooth is extracted or lost, the neighbouring teeth start to tip into the gap, and the tooth in the opposite jaw starts to over-erupt towards it. A tooth that has tipped no longer touches its neighbour in the same place or as tightly. In other words, food trapping is often the silent consequence of tooth loss that shows up months later.

The second group of causes has to do with the structure at the contact point itself. A worn filling or one with a broken edge, decay that has started at the contact point, or a crown whose contact with its neighbour was not built correctly all have the same result. What this group has in common is this: the problem is solved while it is small, and as it grows, both the treatment and the cost grow.

The third is the gum itself. When the gum recedes, the triangular space between two teeth opens and food gets in there. Here the contact point may still be in place; the problem is that the support underneath has receded. In this situation, food trapping can be the first noticeable symptom of advanced gum disease.

A less well-known cause comes from the opposite jaw. When a pointed cusp on the opposing tooth lands exactly between two teeth, it pushes food down like a plunger with every bite. In this situation there may be no visible problem with the lower teeth; the place to correct is that cusp in the opposite jaw.

Food staying trapped there is not harmless. Bacteria build up in the area, the gum becomes inflamed and starts to bleed, and over time a pocket deepens at that point. The deeper the pocket, the harder it is to clean, and as long as it cannot be cleaned, bone loss progresses. Decay at the contact point is also common in the same area. In other words, a minor annoyance that happens twice a day can turn into bone loss within months.

Which situations are easy to solve and which go deeper

The same complaint can have very different causes. The distinction is made with an examination and an X-ray; you cannot tell them apart by looking in the mirror.

The tooth can be saved

The cause is a failing filling or crownThe contact point is rebuilt and closed, and the food trapping ends that day. This is the easiest situation to solve; if it is put off, decay develops underneath, so a simple procedure turns into a bigger job.
Decay has just started at the contact pointOnce the decay is cleaned out and the tooth is sealed, the food trapping ends and the decay stops progressing. Decay in this area cannot be seen with the naked eye; it shows up on an X-ray.
A cusp in the opposite jaw is causing itThe bite is examined and that cusp is reshaped. It takes a few minutes, and you feel the result straight away. It is one of the most commonly missed causes.
Gum inflammation has only just startedWith a professional clean and proper cleaning between the teeth, the tissue returns to health. Nothing is lost at this stage; what decides it is how early you come in.

Saving it is unlikely to hold

The teeth have tipped into the gap left by a lost toothThe contact relationship has changed and may not be correctable with a single filling. The real issue here is not the food trapping but the chain set off by the missing tooth: neighbouring teeth tipping, the opposing tooth over-erupting and the bone shrinking.
The pocket has deepened and bone loss has startedClosing the contact point is no longer enough on its own; gum treatment is needed as well. Because lost bone does not come back, the aim here is to stop it progressing.
Gum recession is advancedOnce the triangular space between two teeth has opened, food trapping continues even if the contact point is still in place. In this situation the solution is not local; it concerns the health of the gums as a whole.
The same area has been treated several timesAt a contact point where the filling has been redone again and again, there is a cause underneath that has been missed: drifting, the bite or gum loss. Rather than repeating the same procedure, the cause needs to be found.

How it is assessed at the clinic

Although the complaint seems simple, the assessment is made up of several steps, because very different causes can lie behind the same symptom.

1
Pinpointing where the food gets stuck
You are asked which two teeth it gets stuck between, on which side and with which foods. What the patient says is very valuable here; the area is usually exactly where the patient points.
2
Testing the contact point
The tightness of the contact between the two teeth is measured with a thin strip. A space the strip slides through without resistance shows directly that the contact has opened.
3
X-ray
Decay at the contact point cannot be seen with the naked eye; it shows up on an X-ray. The same image also shows the bone level in that area and any bone loss.
4
Gum measurement
The pocket depth at that point is measured, and the area is checked for bleeding. This is the key measurement that shows how much harm the food trapping has done to the gum.
5
Examining the bite
We check whether a cusp in the opposite jaw is pushing food down. If this step is skipped, the food trapping continues however many times the lower tooth is treated.
6
Treatment according to the cause
Replacing the filling or crown, cleaning out the decay, adjusting the bite or gum treatment. If a tooth is missing, the real conversation is about how that gap will be dealt with.

What to do and what not to do at home

The lasting solution is at the clinic, but cleaning the area properly until your appointment stops the damage getting worse.

Floss or an interdental brush

These are the right tools. Floss gets past the contact point and removes the trapped food; if the space is wide, an interdental brush works better. Both work by passing alongside the gum, not by pushing it.

A water flosser

A device that washes trapped food away with water. It is especially useful for people with limited manual dexterity. It does not fully replace an interdental brush, but it is many times better than a toothpick.

Not to do: toothpicks

Pressing a hard, pointed object into the gum makes the tissue recede and sometimes injures it. In this situation a toothpick is not the answer but something that speeds the problem up.

Not to do: avoiding the side where food gets stuck

Not chewing on that side reduces the food trapping but does not solve the problem; what is more, it piles all the load on the other side. Chewing on one side only becomes a separate problem over time.

Not to do: putting it off

This complaint does not go away on its own, because the cause underneath does not correct itself. Every month it is put off turns a simple procedure into a bigger job.

The price of delay and the wrong kind of intervention

Because this complaint seems minor, it is one of the signs people put off most. The following are the real consequences of putting it off.

Toothpicks make the gum recede

Forcing a toothpick in to get trapped food out pushes the gum back a little further each time. Gum that has receded does not grow back, and the space that opens makes the food trapping worse. In other words, a toothpick makes bigger the very problem it seems to solve.

Decay at the contact point

Food trapped between two teeth creates an ideal environment for decay in that area. This decay cannot be seen with the naked eye and is usually found on an X-ray, when it is already quite advanced.

Deepening pockets and bone loss

At a point where inflammation is constantly being fed, the gum pocket deepens. A deepening pocket cannot be cleaned, and a pocket that cannot be cleaned leads to bone loss. The end of this chain can be the loss of that tooth.

Bad breath

Food left in the same area becomes the source of a smell. A smell that does not go away with brushing and always comes from the same place is a common sign of this situation.

After treatment

When the cause is correctly identified, you feel the result straight away; if you do not, the cause has not been found yet.

The same day
If the contact point has been rebuilt or the bite adjusted, the food trapping ends that day. There may be slight tenderness in the area for the first few days; this passes as the tissue settles.
The first week
If there is gum inflammation, it starts to settle and the bleeding decreases. You need to keep cleaning the area regularly; leaving it alone because it is inflamed makes things worse.
The first month
The pocket measurement is repeated to assess whether the inflammation has settled. If some depth remains, gum treatment is planned.
The long term
If the cause is tooth loss, this is where the real conversation starts. As long as the gap is not dealt with, the neighbouring teeth keep tipping and the opposing tooth keeps over-erupting; the food trapping comes back at another point.

Message us right away if

Food getting stuck in the same place at every meal. This is not something to get used to but a sign that needs assessing. If you come in early, it can often be solved in a single session.
The gum in that area bleeding or swelling. It shows that inflammation has started. At this stage, treatment solves it without anything being lost; if you wait, the pocket deepens and bone loss begins.
A smell that does not go away with brushing and always comes from the same place. The source is most likely food left in that area or decay that has developed underneath. It will not go away on its own.
The problem coming back even though the same area has been treated more than once. There is a cause underneath that has been missed: the bite, drifting or gum loss. Ask for the cause to be found rather than the same procedure being repeated.

What determines the cost

The same complaint may be solved with a single-session procedure, or it may extend to gum treatment and planning for a missing tooth. These are the items that decide it:

What the cause is: A bite adjustment, replacing a filling, treating decay and a crown are different procedures. An exact figure comes once the X-ray has been seen.
Whether gum treatment is needed: If the pocket has deepened, treatment can move from a local procedure to a plan covering most of the mouth. If you come in early, this item never arises.
The next plan, if a tooth is missing: If the food trapping stems from tooth loss, the real cost lies in dealing with that gap. For patients who decide early, additional surgery does not come into it.
How many areas are affected: A problem limited to a single point and the same problem in several places in the mouth are not the same job. Food trapping in many places is usually a sign of a bigger picture.

Frequently asked questions

Is it normal for food to get stuck between teeth?

Food getting stuck occasionally and in different places can be considered normal. But if it always gets stuck in the same place at every meal, it is a sign: the tight contact between two teeth has opened. It will not correct itself, because the cause underneath does not correct itself.

Can I use a toothpick?

Do not. Pressing a pointed, hard object into the gum makes the tissue recede; gum that has receded does not grow back, and the space that opens makes the food trapping worse. The right tools are floss and an interdental brush; both work by passing alongside the gum, not by pushing it.

I use floss, but food still gets stuck. What should I do?

Floss cleans out trapped food; it does not repair the contact point. The cause of food trapping is a mechanical gap, so however much you floss, it happens again at every meal. For a lasting solution, the contact point, the bite or the gum needs to be assessed.

Can food trapping cause toothache?

It can. Trapped food presses on the gum, and there may be a feeling of pressure, throbbing or pain on biting in that area. Also, when decay developing at the same point progresses, the tooth itself becomes the direct source of pain.

I have a missing tooth. Could that be linked to food getting stuck?

Most likely, yes. When a tooth is lost, its neighbours tip into the gap, the tooth in the opposite jaw over-erupts and the contacts between the teeth break down. This is one of the silent consequences of tooth loss that show up months later, and it keeps progressing as long as the gap is not dealt with.

Can food trapping cause bad breath?

It can. Food left in the same area is a constant source of nourishment for bacteria. A smell that does not go away with brushing and always comes from the same place is one of the common signs of this situation.

Is your protocol right for me just for this complaint?

No, and let us say so plainly. Food getting stuck at a single point is something to be solved with your own dentist. Our protocol is for many missing teeth and the full mouth. However, if food trapping is widespread and several teeth are missing, the picture changes, and then there is a different conversation to have.
