What Is a Cavity?

A cavity, also known as tooth decay, is a hole in your teeth.

Cavities are caused by the buildup of plaque, a sticky film of bacteria that constantly forms on your teeth.

Plaque produces acid that attacks the tooth enamel, causing it to break down and create a cavity.

If left untreated, cavities can become more extensive and lead to pain and infection. In severe cases, they can even cause teeth to fall out.

Cavities are one of the most common dental problems but are also preventable. With proper oral hygiene and regular dental visits, you can help keep cavities at bay.

Cavity Signs & Symptoms

The most common symptom of a cavity is tooth pain which occurs when tooth decay breaks through the hard outer layer of the tooth (enamel) and reaches the softer second layer (dentin).

The inner layer (pulp) houses blood vessels and nerves that extend into the dentin.

Cavities are one of the most common dental problems but are also preventable.

With proper oral hygiene and regular dental visits, you can help keep cavities at bay.

Cavity Treatment Solutions (In-Office)

Many people think the only way to fix a cavity is to go to the dentist and have a filling.

However, you can repair cavities at home. One way to fix a cavity is by routinely using toothpaste that has fluoride in it.

Fluoride helps prevent cavities from forming in the first place, so it can be helpful to use toothpaste that contains fluoride even after you have a cavity.

If you have a cavity-causing you pain, you may need to have a dentist fill it. However, if the cavity is not causing you pain, you may be able to reverse the cavity at home with one of the methods described below.

How to fix a cavity in the front tooth?

If you have a cavity in your front tooth, you may be concerned about the appearance of your smile.

However, there are several treatment options available that can help to restore the function and appearance of your tooth.

Treatment Options

  • Filling: An affordable option that requires minimal tooth structure removal and can last years. It prevents further decay and restores tooth strength.
  • Veneer: Porcelain veneers, bonded to the tooth’s front, can hide stains, chips, and imperfections. They’re usually more costly and not typically covered by insurance.
  • Crown: Ideal for extensive cavities, a crown encases the tooth, providing strength and protection. Matching a crown to the adjacent tooth can be tricky, so crowning both front teeth might be suggested.

How to Fix a Cavity Between Teeth?

Most cavities form between teeth because cleaning is the most challenging area.

Brushing alone will not remove the harmful bacteria lodged between teeth. Flossing or using a Waterpik are the best ways to clean between teeth because they physically remove the cavity-causing bacteria.

Flossing is preferred; however, using a Waterpik is recommended if you have significant gaps between your teeth.

Chances are, if you have a cavity between your teeth, you’ll need to see a dentist to fill it, as it is more challenging to remineralize (heal) than a cavity on a smooth tooth surface.

What Is Prescription Fluoride Toothpaste?

Your dentist can only prescribe prescription fluoride toothpaste and contains a higher fluoride concentration (5000 ppm).

This maximum-strength toothpaste reduces cavity risk by 42%, whereas over-the-counter fluoride toothpaste reduces cavity risk by 23%.

Key Benefits

  • Reduces risk for tooth decay
  • Decrease tooth sensitivity
  • Prevent cavities from growing
  • Remineralize (heals) small cavities
  • Minimally abrasive toothpaste

Best Patients

  • Patients with braces
  • Patients with active tooth decay
  • Patients with dental hypersensitivity
  • Patients with high cavity risk (prone to tooth decay)
  • Patients with dry mouth
  • Patients with exposed root surfaces
  • Patients with many fillings and crowns

Can You Reverse a Cavity?

If the cavity is in the enamel layer ONLY, it can likely be reversed and healed (also referred to as remineralized) because the tooth can replace minerals that have been lost.

However, if the cavity has reached the dentin layer (second layer), it’s much harder to treat and heal naturally. In this case, you’ll likely need to see a dentist and fill the cavity.

How long does it take to reverse a cavity?

The time it takes to reverse a cavity naturally depends on its depth.

For example, if the cavity is in the superficial enamel layer only, it can often be reversed quickly (within a few weeks). However, if the cavity has reached the junction with the dentin layer, it will take longer to reverse (several months to a year).

Other factors to consider include diet, oral health, frequency of sugar consumption, frequency of dental visits, and genetics.

Can cavities go away with brushing?

Cavities cannot go away with brushing alone, but you can prevent them from worsening.

Brushing removes the plaque and bacteria that cause cavities and helps remove the food particles that contribute to them. However, once a cavity has formed and entered the second tooth layer (dentin), a dentist can only remove it.

Can salt remove a cavity?

No, salt cannot remove a cavity.

However, it can help prevent cavities by killing the bacteria that cause them. Salt also helps to remove the food particles that contribute to cavities.

To use salt as a cavity prevention method, add a teaspoon of salt to a cup of warm water and swish it around your mouth for two minutes. Then, spit it out and rinse with water.

How long can a cavity go untreated?

Cavities can go untreated for a long time but eventually become painful.

The longer a cavity is left untreated, the more damage it will do to the tooth. If the cavity damages most of the tooth structure, the tooth may need to be extracted (pulled out).

Some cavities progress faster than others for reasons including genetics, diet, oral health, and frequency of sugar consumption.

What Does a Cavity Look Like?

Cavity on x-ray | How to Fix a Cavity: Treatment Solutions & Costs | My Dental Advocate

Cavities are often small, dark spots on teeth. In the early stages, a cavity may not be visible to the naked eye and may only be detected through dental x-rays.

However, cavities will become more prominent and apparent as cavities progress.

Cavities routinely form on the chewing surface of the teeth in the grooves and pits.

This area is difficult to clean and will begin to harbor bacteria. Stains in the teeth will also be an early sign of tooth decay.

What does a cavity look like on an x-ray?

On an x-ray, a cavity will look like a dark shadow. This occurs because the cavity eliminates much of the healthy tooth structure allowing the x-ray beam to pass through and emit a dark shadow.

The larger the cavity, the easier it is to spot it on the x-ray.

Digital x-rays allow the clinician to utilize tools to evaluate the x-ray, including magnification, sharpness control, and color changes.

Cavity Treatment Costs

The cost of filling a cavity depends on the size, location, and type of filling material used.

For example, the average price of a silver amalgam filling is $50-$150, whereas the average cost of a composite resin filling is $90-$250. Gold or porcelain fillings are usually more expensive, costing $500-$4,000 per tooth.

A veneer or crown will be indicated if the cavity extends across more than half of the tooth or causes an irreversible stain, a veneer or crown will be indicated.

The average cost of veneers is $700-$2000, whereas the average price of crowns is $500-$3000.

The cost of the veneers ranges in price due to porcelain/ceramic material differences, practice location in the country, and dentist expertise. Cosmetic dentists specialize in esthetic treatments such as veneers and crowns, so they often charge more for their services.

Crowns range in price due to crown material choice, practice location in the country, and insurance coverage. Porcelain-fused-to-metal (PFM) crowns are often the cheapest material, whereas zirconia or porcelain/ceramic crowns are the most expensive.

The cost difference is also due to differences in material strength, lab cost, and same-day crown treatments.

How to Prevent Cavities

Preventing tooth decay can save you time in the dentist’s chair, hard-earned money, and unnecessary pain.

Recommendations

Step 1: Brush Twice Daily

Brushing removes food particles and plaque, which can turn into calculus and cause cavities. Brush at least twice a day to maintain oral health.

Step 2: Use Fluoride Toothpaste

Fluoride strengthens enamel and prevents cavities. It’s crucial for remineralizing teeth and stopping cavity progression, so use fluoride toothpaste.

Step 3: Floss Daily

Flossing gets rid of plaque and bacteria between teeth and under the gumline, areas your toothbrush can’t reach. This helps prevent cavities in these spots.

Step 4: Regular Dental Visits

Seeing your dentist regularly helps catch early signs of decay, plaque buildup, or gum inflammation. Professional cleanings and checkups are key.

Step 5: Balanced Diet, Limit Sugary Foods

Sugary and acidic foods harm teeth. Limit these and maintain a balanced diet with plenty of water for healthier teeth.
