Do cavities go away after filling?

Yes, cavities go away after filling but they can return if good oral hygiene is not maintained.

In order to prevent cavities from reappearing even after filling, daily brushing your teeth twice is essential along with daily flossing and occasional mouthwash.

What Is A Dental Filling?

Dental filling, as the name suggests, is the use of various materials to fill the hole in the teeth called cavities

Materials used to fill the cavities are referred to as Filling Materials and the process is known as Dental Filling.

How Is A Dental Filling Done?

  1. A local anesthetic is used in the first step to numb the soft tissues around the tooth that needs filling. This is essential to give painless dental care.
  1. Removal of the decayed area of the tooth that needs filling using rotary instruments, or a laser.
  1. Probing to confirm removal of all decayed parts of the tooth that needs filling.
  1. After complete removal of the decayed part, cavity preparation is done by cleaning the bacteria and other debris produced during decay removal.
  1. Liners are applied for nerve protection if the decay has advanced to the root and might irritate the nerve endings.
  1. If you have opted for a tooth colored composite material for filling, then your dentist will apply the composite in layers and use a special blue light called “curing” to harden the composite material applied.
  1. Finally, trimming and polishing is done and the filling process is complete.

Different Dental Filling Materials To Choose From: What Is Best For You?

Variety of materials are used for filling. Some of them are listed below:

  • Gold fillings 
  • Porcelain 
  • Silver amalgam  
  • Tooth-colored materials called composite resin fillings
  • Glass Ionomer

Several factors that need consideration while choosing the best filling material for yourself are:

  • Where is the decay located?
  • How much decay has involved the tooth?
  • If the roots are involved?
  • Amount you can bear for a filling?
  • Recommendation of the dentist after full examination and X-Ray

After taking all the above points in consideration, you can choose the best filling material for yourself that will have maximum efficacy and minimum discomfort.

Ways To Heal Dental Cavities Naturally

If the cavity is just in its initial stage where the white spot is visible on the tooth, it is the time to take preventive actions such as toothbrushing, mouth washing and flossing daily.

At stage one, when the white spot has just appeared, the cavity can be reversed with proper oral hygiene and eating some mineral and vitamin rich foods.



It is recommended by the American Dental Association (ADA) to  brush your teeth twice a day for two minutes each time with a toothpaste containing fluoride. 

It is recommended to brush your teeth twice a day, once in the morning, just after waking up and once at night, just before going to bed.

You must also clean your teeth and gums, each time after you have food but not with a toothbrush. Simple rinse with water is considered good for overall oral health and hygiene.

Following this tooth brushing habit will help you prevent cavity formation in the first place and also heal a small cavity naturally in its earliest stage.

Do Not Immediately Brush after Eating Acidic Foods

You must wait for 30 minutes to one hour after consumption of acidic foods and drinks. The acid in the food or drink otherwise may erode the enamel layer and regular habit may cause exposed dentin leading to pain and sensitivity and increased risk of developing cavities.

Use Gentle and Short Strokes When Brushing Your Teeth

Use gentle, short strokes to brush your front teeth and thoroughly clean your mouth without abrading the enamel and preventing cavities from developing.

Brush the outside surfaces as well as the back molars and upper areas of your chewing surfaces. Brush the inside surfaces of both top and bottom front teeth by flipping your toothbrush upside down.

Brush your tongue to get rid of any bacteria or plaque.

Use a fluoride toothpaste

Fluoride can greatly help achieve oral and dental health by strengthening the tooth enamel, making it more resistant to tooth decay. 

Fluoride reduces the amount of acid produced by the bacteria on your mouth and also helps the cavity in its earliest stage to repair and heal. 

Floss Daily To Get Maximum Benefits Out Of Tooth Brushing

Many people, despite knowing the benefits of flossing daily, just neglect it.

According to a study, flossing is highly effective in reducing the interproximal caries risk. 

Daily floss can help stimulate your gums and reduce plaque leading to lesser inflammation risk and increased healing process of the cavity in its earliest stage.

Consider mouthwash

Therapeutic Mouthwashes contain ADA listed active ingredients such as fluoride, peroxide, essential oils, cetylpyridinium chloride, and chlorhexidine, preventing cavities from forming and naturally healing the formed cavity in its earliest stage.

Therapeutic mouthwashes as the name suggests have therapeutic action and control dental conditions like gingivitis, tooth decay and periodontal diseases. They also help remove halitosis.

Consult Your Dentist Twice In A Year

It is important to get your oral health checked twice every year with an interval of 6 months between two visits.

Your dentist can help remove calculus and locate cavities and will also be able to spot potential oral health issues, if any, and offer treatment solutions.

Fluoride treatments initiated in the earliest stages of tooth cavity may help it to reverse and heal.

Eat Foods Rich In Calcium, Magnesium, Phosphorus And Vitamins To Heal Cavities Naturally

Calcium Rich Foods To Heal Cavities Naturally

Calcium plays an important role in enamel remineralization and saliva production.

The remineralization process is essential for the cavity to reverse naturally.

Optimal saliva production acts as a natural cleanser and prevents plaque accumulation and acts as an adjunct in the process of healing cavity naturally.

All thanks to calcium rich foods like cauliflower, nuts, salmons and figs.

Magnesium Rich Foods To Heal Cavities Naturally

Magnesium is essential for remineralization of the enamel as well as to maintain a balance of minerals like calcium and phosphorus.

Magnesium deficiency will lead to enamel demineralization and weakening of the enamel, halting the natural healing of the cavity.

Leafy green vegetables, avocado and squash seeds are some magnesium rich foods that you can consider.

Phosphorus Rich Foods To Heal Cavities Naturally

Foods like meat, eggs and dairy products are rich in phosphorus and help in naturally healing the cavity in its earliest stage.

Vitamin D Rich Foods To Heal Cavities Naturally

Vitamin D is essential for calcium and phosphorus absorption in the body and its deficiency eventually wastes the calcium you intake.

Spending a few minutes in the morning sun gives an adequate amount of vitamin D to the body. However, foods like fish and egg yolks are rich vitamin D sources.

Vitamin D And Cavity Prevention: What Research Says?

According to research, children with vitamin D deficiency had an increased risk of developing enamel defects and tooth fracture.

Another clinical trial reported vitamin D to be a prominent agent for caries prevention.

Study published in the journal of dental research, concluded that vitamin D is essential for lowering the risk of developing caries in children.
