How Long Can You Leave a Cavity Untreated?

How long can you leave a cavity untreated? Enamel decay can go untreated for a year since cavities form slowly and can be corrected. The re-evaluation needs a dentist’s exam and x-rays to see if the cavity has developed.

How Long Can You Leave a Cavity Untreated?

What Is a Cavity?

Ultimately, cavities are just decay caused by bacterial overgrowth. If left untreated, this can expose the more delicate inner layers of teeth, causing excruciating agony.

Cavities develop when teeth aren’t properly cleaned, allowing germs that can’t be destroyed by toothpaste to thrive. They thrive on the sugars in sweet foods like chocolate and ice cream, which they utilize to manufacture the acid that wears away at tooth enamel and causes discomfort.

It’s annoying to deal with cavities, but how dangerous are they? I was wondering how long a cavity may go untreated. Of course, they need to be addressed, but how long can you put it off? We’ll explain it and more down below.

What Happens If I Leave a Cavity Untreated?

Not getting a cavity filled at your regular dental visits might lead to a few problems.

Sensitivity Boost:

If you’ve developed a cavity, you’ve probably noticed that your tooth is more sensitive to hot and cold conditions. Some of you may have noticed that your morning cup of coffee doesn’t become as hot as it used to.

That glass of lemonade may not be so pleasant on a hot summer day if it gives you a toothache. This is your body telling you that you have a problem with a tooth that needs immediate attention.


With time, you’ll experience increasing discomfort whenever you utilize that tooth. The discomfort is sudden and persistent and occurs no matter what you’re eating, whether it’s a soft marshmallow or a meal. Your teeth are aching. Therefore it’s time to make an appointment with the dentist.


If bacteria enters the pulp of your tooth, you may develop an abscess. This may cause some edema. See a dentist soon before it becomes a serious problem, as your body is trying to warn you. That swelling is a result of the inflammation in your mouth.

Possible Necessity for a Root Canal or Extraction

You may need a root canal or an extraction if you ignore the problem. An infection causes damage like this in the pulp of your tooth. When a tooth is badly damaged or decayed, a root canal may be the only way to save it from being pulled. If the damage is too great, extraction may be necessary.


The tooth will be extracted in its entirety in this case. The greatest way to ensure your long-term health is to get any cavities found by a dentist as soon as possible. If you have a cavity, seeing a dentist can help you deal with the situation and have it fixed.

How Long Can You Leave a Cavity Untreated?

If a tooth has decayed to the dentin but not yet to the pulp, treatment should begin as soon as possible, ideally within a few weeks. Cavities in dentin spread more quickly than in enamel and are permanent, which is why a shorter time frame is used.

The rapid development of dentin.

The dentin lacks the mineral hydroxyapatite, responsible for enamel’s hardness. Hence it is not as durable. This means that cavities in the dentin will progress at an exponentially higher rate. Because of how quickly it spreads, decay should be stopped before it gets out of hand.


Cavities confined to the enamel can be treated, but those that have progressed into the dentin cannot. This implies that you won’t be able to prevent or reverse tooth decay even if you wash your teeth twenty times a day using fluoride toothpaste. As a result, there is little use in putting off treatment for an irreversibly advanced illness.

If a cavity is detected within the enamel, how long before it has to be treated?

Caries confined to a tooth’s enamel can be left untreated for up to a year before the further assessment is necessary. An x-ray and a dentist’s examination are needed for the reevaluation to determine if the cavity has worsened. Enamel decay can go undetected for up to a year due to two factors: cavities form slowly in enamel, and the decay can be reversed if caught early enough.

  • Enamel development is very slow - Because tooth enamel is the toughest component in the body, decay moves very slowly while it’s still in the enamel. Since enamel has a higher concentration of hydroxyapatite than bone, it is far more resistant to wear and fracture. Since enamel is so resistant to breakdown, it takes a lot of time for germs to bore through your tooth and invades the dentin underneath.

  • Reversible - Cavities in the enamel can be prevented and even rectified in some cases. Fluoride and hydroxyapatite are two components of toothpaste that have been shown to reverse cavity formation. Since the cavity may heal independently, waiting to fill it might be beneficial.

These two elements are responsible for the sluggish development of enamel cavities and the subsequent delay in therapy. Even if you can put it off for a while, it doesn’t mean you should.

Can a Cavity Go Untreated for How Long?

This is true of most medical conditions in the same way that a cavity will worsen if left untreated for too long. Cavities can spread to the tooth’s pulp in as little as three to six months. In a word, no. This is a really bad situation.

That’s also not a rock-solid argument. What you put in your mouth and how well you take care of your teeth are the two biggest factors in how soon a cavity might progress. Cavities will progress much more rapidly if you combine a diet high in sweet foods with inadequate dental hygiene.

Your best action is to get a cavity filled as soon as possible to prevent further discomfort. Even more so now, as the end of the year approaches and dental benefits change, making it a good opportunity to use them up before the new year begins.


You’re not alone if your fear of the dentist keeps you from filling that cavity. People are afraid of the dentist for similar reasons, but if you tell them ahead of time that you suffer from dental anxiety, they can take steps to make your appointment less terrifying.

How do Dentists treat Cavities?

Fillings are the standard method of cavity treatment. Local anesthetic or “freezing” will be used to numb the region around the damaged teeth to guarantee that you feel no discomfort during the process.

After the deterioration is eliminated, the void left behind will be filled with a suitable substance. The traditional metals for this function are silver and gold, although it’s more customary to utilize porcelain or resin that looks quite similar to the real thing.

Since the end of the year marks the end of the benefits period for many people, now is the time to get any holes filled.

Why Is Cavity Treatment So Important?

To put it simply, a cavity will not heal itself. Untreated dental decay will worsen if allowed to progress.

Untreated cavities can spread as described below.

  1. Plaque on a tooth weakens the enamel and causes a cavity to grow. Teeth have an exterior coating of enamel that is both hard and protective. Fluoride treatments at the dentist’s office can protect your teeth from decay.

  2. When a cavity first appears, it affects only the outside layer of the tooth, called the enamel. Most people’s pain thresholds have been permanently raised at this time. The only way to detect a cavity is with routine dental examinations.

  3. Third, the cavity will extend to the dentin if it is not treated while still in the enamel stage.

  4. The pulp and nerves of your teeth are affected by a cavity because it progresses through the tooth to the deepest layer.

  5. An abscess from infected pulp can be unpleasant and may make the affected area sensitive to temperature changes. Your dentist may try to salvage the tooth with a root canal, but if unsuccessful, they’ll have to pull it.

"Untreated cavities will worsen over time. Eventually, the decay will spread behind the enamel and reach the tooth’s pulp. This can lead to severe decay, infection, and eventual tooth loss "Columbia University Irving Medical Center Professor of Dental Medicine John Grbic, DMD.

Keep in mind: Additional problems may arise if a cavity is not untreated. In extremely unusual and extreme circumstances, death can occur if infection from a rotting tooth spreads to the brain and isn’t treated.


1 - When is it too late to reverse a cavity?

If you wait until you see the dentist to treat tooth decay, it will usually be too late to use just natural remedies. You should see a dentist every way to stop the decay from spreading to the rest of the tooth.

2 - What happens if you don’t get a cavity filled?

The consequences of not having a filling. Damage to a tooth’s enamel caused by decay cannot be repaired. The cavity will worsen and spread to adjacent good tooth structures if not addressed.

3 - How long may a cavity go untreated?

Learning to recognize the signs that a cavity requires filling. A cavity might grow over five years before it becomes severe enough to warrant treatment to save the tooth. However, that time frame could just be a few months for certain individuals.

4 - How long does a cavity go without treatment?

In certain persons, germs and acid can easily enter the tooth enamel. It may take from 4 months to 5 years before a cavity has to be treated, but this is only an estimate. Day by day, the state of your mouth will vary.

5 - How much time does it take for a cavity to ruin your tooth?

The rate at which a cavity may damage a tooth is unpredictable. Neglected dental decay, especially if left untreated for a long time, can cause significant structural damage to teeth. Tooth decay may be prevented before it reaches this advanced stage with regular dental examinations and care.

6 - What does the first stage of a cavity look like?

It may be difficult to spot a cavity early on, although some develop a yellowish or chalky look on the tooth enamel. Brown or black discoloration may appear in more severe instances. Unfortunately, though, there are rarely any clear warning signs.

7 - Can cavities go away on their own?

The decay in your teeth, known as a cavity, won’t just go. An eventual root canal may be necessary if a cavity causes enough discomfort to spread into the tooth’s pulp and pulp chamber. So, if you find a cavity, you should visit the dentist as soon as possible.

8 - Can teeth that are decaying be saved?

A tooth’s deterioration and decay can be slowed with some treatments, but once it has begun, it cannot be undone. A fluoride treatment performed by a dentist can strengthen or remineralizer a tooth in the early stages of tooth rot (small cavity), perhaps halting the spread of the cavity.

9 - Is there any long-term damage from putting off filling a cavity?

If left untreated, cavities can lead to discomfort and infections, which can affect a person’s ability to eat, speak, play, and learn. An abscess (a severe infection) behind the gums results from untreated cavities and can spread to other areas of the body, causing severe and, in extreme circumstances, lethal consequences.

10 - Do Cavities Get Better With Salt Water?

If you have a cut or infection in your mouth, your dentist or surgeon may suggest gargling with saltwater. The germs that cause cavities can even be killed by saltwater. When you uncover a cavity, rinsing with salt water might help prevent it from worsening as quickly.


To sum up, the length of time a cavity can go untreated depends on the advancedness of the decay. If the cavity is limited to the enamel layer, further evaluation is not required for up to a year. If decay has spread into the dentin or pulp, immediate action is necessary before the tooth is irreparably damaged.

Because of this disparity, enamel decay can be left untreated for longer than deterioration in the dentin and pulp. Thus regular dental checkups every six months are highly recommended. There is a potential that fluoride or hydroxyapatite toothpaste might help you reverse the effects of this if you are so fortunate.
