How to Repair Cavity at Home

Table of Contents

 Cavities are a common dental issue that affect people of all ages. They occur when bacteria in the mouth produce acid that eats away at the tooth enamel. This can lead to tooth decay, pain, and even tooth loss if left untreated. Fortunately, there are steps you can take to repair a cavity at home.

Tooth Cavity Repair

What You'll Need

Before you get started, you'll need a few supplies:

  • Toothbrush
  • Fluoride toothpaste
  • Dental floss
  • Salt
  • Water
  • Clove oil

Step 1: Brush and Floss Regularly

The best way to prevent cavities is to brush and floss your teeth regularly. This will help remove plaque and bacteria from your teeth and gums, reducing your risk of developing cavities in the first place.

Step 2: Rinse with Salt Water

If you already have a cavity, rinsing your mouth with salt water can help reduce inflammation and kill bacteria. Mix half a teaspoon of salt with a glass of warm water and swish it around in your mouth for 30 seconds before spitting it out.

Step 3: Apply Clove Oil

Clove oil has natural analgesic and antibacterial properties that can help relieve tooth pain and fight infection. Dip a cotton swab into the oil and apply it directly to the affected tooth and surrounding gums. Be sure to dilute the oil with a carrier oil like olive oil or coconut oil to avoid irritation.

Step 4: Use Fluoride Toothpaste

Fluoride is a mineral that helps strengthen tooth enamel and prevent cavities from getting worse. Use a fluoride toothpaste when you brush your teeth to help repair the cavity and protect your teeth from further decay.

Pros and Cons of Home Cavity Repair

While home cavity repair is a convenient and affordable option, it's important to consider the pros and cons before attempting to fix a cavity on your own.


  • Cost-effective: Home remedies for cavity repair are often much cheaper than professional dental treatments.
  • Convenient: You can perform these remedies at home without having to schedule an appointment with a dentist.
  • Natural: Many home remedies use natural ingredients that are gentle on your teeth and gums.


  • Not guaranteed to work: Home remedies may not be as effective as professional dental treatments and may not be able to completely repair the cavity.
  • Can be risky: Attempting to fix a cavity at home can be risky if you don't know what you're doing or if you use the wrong materials.
  • No professional guidance: Without the guidance of a dentist, you may not know how to properly diagnose and treat your cavity.


Q: Can a cavity heal on its own?

A: No, a cavity cannot heal on its own. Once a cavity forms, it will continue to grow and worsen until it is treated by a dentist.

Q: How do I know if I have a cavity?

A: Common signs of a cavity include tooth sensitivity, pain when eating or drinking, visible holes or pits in the teeth, and dark stains on the teeth.

Q: Can I use baking soda to repair a cavity?

A: While baking soda has natural whitening properties, it is not effective at repairing cavities. It's best to stick to fluoride toothpaste and other proven cavity-fighting methods.

Q: How long does it take to repair a cavity?

A: The time it takes to repair a cavity depends on the severity of the decay. In some cases, it may only take one dental visit to fill a cavity. In more severe cases, multiple visits may be necessary.
