Holes sometimes form on your tooth’s surface because of damage from tooth decay. These holes are known as dental cavities, or caries, and they affect 90 percent of American adults.

What you do when you have cavity depends on how serious it is when you discover it. A trip to the dentist is the first step, followed by any home remedies you want to try ahead of your dental visit.

If you do not experience any pain, you can get away with caring for the tooth with regular brushing and flossing. (Although be careful with that tooth.)

If pain is part of the problem, over-the-counter numbing gels can help.

Once you get to the dentist, you are likely in store for a filling, a crown or a root canal to fix that hole.

Causes of a Hole in Your Tooth

Tooth holes form mainly because of sugary food and bacteria that are ever-present in your mouth. Some bacteria are harmless (normal flora), while others are harmful. 

When harmful bacteria interact with the sugary food, they form plaque, an acidic component that erodes your teeth. Plaque accumulates if you don’t clean your teeth after meals. If it is not removed, plaque eventually creates holes in your teeth.

Holes can also result if you clench and grind your teeth (bruxism). Night-time teeth grinding is common but should be treated.

Constant grinding can crack your enamel (the white part of your teeth), and those cracks can grow large enough to form tooth holes.


In the early stages of tooth decay, you might not experience any symptoms. Time will take care of that if you are not taking care of your teeth with regular brushing and flossing.

But the early signs of the cavities include white spots forming in the affected areas of the teeth, indicating that the is breaking down. An early hole appears, displaying a light brown color. 

The tooth decay will progress to its middle and late stages. You could experience one or more of the following symptoms:

  • Severe pain from the affected teeth
  • Sensitivity to foods that are too cold or hot
  • Facial swelling
  • Pus formation around the affected teeth


Holes in your teeth can cause permanent damage if left untreated. Treating the cavities depends on their severity, but treatment options include:

  • Home remedies
  • Fillings
  • Crowns
  • Root canals
Home remedies

Some online content suggests that home remedies can treat tooth decay, but this is not true. There is no way to fill up a tooth cavity or treat it at home.

The best you can hope for is relieving the symptoms of the teeth cavities. It would be best to visit the dentist for proper tooth hole treatment.

However, there are drug store products that can help you deal with any pain associated with the cavity. Over-the-counter numbing gels can help. So can warm saltwater rinses.

Dental Fillings
Dentists can use a refilling material such as resin to restore the eroded surface of teeth. The dentist first removes the decayed part of your teeth then refills the holes using a dental filling.
If the cavity has progressed to most parts of your teeth, you might need a crown replacement. The dentist first removes damaged and undamaged parts of your teeth and then fits an artificial tooth crown into the regions of the affected teeth.
Root Canal
Root canals treat cavities severe enough to have reached your tooth’s pulp, which is the inner part of your teeth. During the procedure, the dentist first removes the damaged pulp and replaces it with a filling.

Complications if Untreated

If you notice any holes in your teeth, take immediate action and treat them. It will help you avoid some dental complications such as:

  • Bone loss or osteoporosis
  • Tooth fracture
  • Bone infection
  • Tooth abscess
  • Severe toothache 
  • Difficulty chewing, which might cause nutritional problems


Dentists will ask about the extent of pain you are feeling, then conduct a physical examination to observe the nature of the holes. A tooth exam will require the following instruments:

  • Light source 
  • Dental mirror 
  • Explorer

Dental radiographs (X-rays) are also necessary, especially if the cavities are between the teeth.


One of the best ways to prevent tooth holes is regular brushing. Other ways of preventing tooth holes include:

  • Adjust your diet. Cut back on foods and drinks with many sugars. Also, avoid those foods that tend to stick to your teeth. Drinking water between meals will help rinse your mouth of excess sugars.
  • Floss. Brushing youth teeth without flossing is only half the job done. Flossing helps clean parts of your teeth you cannot access with a toothbrush.
  • Avoid smoking. Smoking tobacco is one of the main reasons behind many oral ailments, including dental caries.

Risk Factors

In most cases, cavities come from poor dental hygiene. However, you might be more susceptible to it than others because of the following factors: 

  • Poor diet. Your chances of getting tooth holes increase if you take in a lot of sugary foods as it provides fuel to form the acidic plaque that causes tooth decay.
  • Low saliva production. Saliva is crucial to washing the plaque from your teeth. It also has properties that counteract the plaques’ acidic effects. Some drugs, such as antidepressants and muscle relaxants, can reduce your saliva production. 
  • Young or old. Infants and toddlers, especially those who drink from bottles, are at a higher risk of developing cavities. If you are an older adult, your chances increase because of receded gums and worn-out teeth.
  • Low fluoride consumption. Fluoride is an essential compound for your teeth. It helps strengthen them, preventing damage by tooth decay.
