As someone who is passionate about dental health and hygiene, it is important to me to share the knowledge I have with others. That is why I have compiled a list of home remedies for cavities for you to turn to for advice. Keeping your teeth in tip top shape is important for long lasting dental health and a healthy smile. Turning to home remedies for cavities is not only easy, but gentle and highly effective ways to heal cavities naturally.


Cavities, also known as caries, are little holes that appear in the tooth and are caused by a decay in the tooth or teeth that are affected. What causes tooth decay you might ask? Tooth decay can be caused by a bacterial infection. This bacterial infection will cause the affected tooth to become demineralized and destruct the hard tissues within the teeth.

There are certain risks associated in developing cavities. You can develop a cavity from several different factors which includes:

  • Food that will cling to your teeth for long periods of time
  • Frequent sipping or snacking
  • Dental hygiene that is poor
  • Lack of proper amounts of fluoride
  • Dry mouth
  • Worn out fillings or other dental devices
  • Developed eating disorders such as bulimia or anorexia due to the constant purging. (The stomach acids in the vomit will eventually break down the enamel placing the teeth at high risk for developing cavities.)
  • Weakness in the teeth due to lack of proper diet
  • Damaged teeth that have not been looked after
  • Diets lacking calcium, magnesium, or phosphorus

Understanding the causes of cavities will allow you to understand how to prevent cavities. Cavity prevention is essential in dental health and hygiene. Yet, before I go on to cavity prevention, let’s have a look at the signs and symptoms of cavities so you can understand what a cavity will do.


When you have a cavity as an adult, you will know. However, cavities in children can be harder to identify. This can be due to the fact that they do not realize they have one. Not to mention, their teeth are smaller so it can be tricky to spot. Yet, if you are aware of the signs and symptoms, not only can you quickly identify a cavity in a child, you can recognize a cavity appearance in your own mouth.

The signs and symptoms of cavities include:

  • Toothache
  • Tooth sensitivity to cold and/or hot temperatures
  • Sharp or mild pain when drinking or eating
  • Visible pits or holes in the affected tooth
  • Black, white, or brown staining on the affected tooth

If you allow your cavities to go without treatment, they can develop into more serious problems. This includes tooth decay, severe toothaches, infections, and even losing the affected tooth. When this occurs you will need to seek the professional advice of your dentist for professional (and expensive) treatments such as root canals, fillings, and/or crowns.

If you have noticed your child or yourself developing any of the above listed symptoms, you should go to a dentist for a medical diagnosis. With a dental check-up you can determine how serious the cavity is and receive a proper diagnosis. It is advised to speak to your dentist before administering any tooth decay treatment at home.


Treating cavities at home is simple and easy. Not to mention that home remedies are also gentle and powerful and can even be used on babies or young children. After you have received a diagnosis of a cavity, you can begin to use a home remedy for cavities right away.

Any of the above listed home remedies for cavities can be used on children, just be sure to find one that agrees with your child as some of them have a stronger taste than others. In addition to helping to cure cavities and tooth decay in adults and children, the above listed home remedies are also great for treatment for baby bottle tooth decay in children.

In case you are not aware of this condition, baby bottle tooth decay is a term given to the condition that develops in babies and toddlers who are developing teeth, yet are already suffering from tooth decay due to the high sugar contents of a juice or bottle given to them. Babies and toddlers are susceptible to developing baby bottle tooth decay since they will be regularly using a bottle and they are constantly drinking or sipping throughout the day without rinsing their mouths with water.

In addition, many parents make the mistake in assuming babies and toddlers do not require dental care. This cannot be further from the truth. If teeth are present in the mouth, even if they are baby teeth, oral hygiene and care are important for the proper development and health of the teeth and mouth.

Combining any of the above home remedies for cavities can also be implemented, depending on the severity of your cavities or tooth decay, personal preference, and dental recommendations. There are also several tips you can keep in mind so you have optimal dental health and prevent further cavities from developing.

Tips for better dental hygiene and to prevent more cavities from developing include:

  • Regularly use a mouthwash that is antibacterial. This will enable you to fight off bacteria, plaque, and even prevent gum disease.
  • Rinse your mouth with slightly warm water any time after eating a snack or drinking something that is not water.
  • Cut out sugary foods, candy, and sodas from your diet or reduce your intake of these products.
  • Make sure to brush 2-3 times per day.
  • When you brush ensure you are using gentle and circular motions.
  • Make sure to floss at least once per day to help remove plaque, bacteria, and any food stuck in between the teeth and gums.
  • Drink black or green tea to prevent plaque build-up on the teeth.
  • After drinking any drinks that are acidic, make sure to rinse your mouth with warm water to help remove the acids from your teeth and enamel.
  • Drinking cranberry juice often will help to promote dental health.
  • Make sure you are getting plenty of vitamin d – whether it be through exposure to the sun, eating plenty of diary, or even taking a supplement.
  • Chewing sugar free gum will aid in saliva production which will help prevent dry mouth, remove any food particles in the teeth, as well as prevent cavities.
  • Drink plenty of water each day. The water will help to rinse away anything left on the mouth and increase your saliva production. You will also prevent dry mouth and bad breath with regularly drinking water.
  • Make sure your diet is high in fiber, vitamins, and minerals so you can be at optimal health and fight infection naturally as well as increase your saliva production.

Keeping a healthy smile will leave you wanting to smile even more. And smiles are very contagious. This is why I am passionate about oral health and hygiene and with the help of home remedies for cavities you can be sure to achieve the best natural dental health for you and your family. Keeping high levels of dental health are vital to ensure you have long lasting gum and tooth health.

After your baby teeth, you only get one chance to keep your teeth for the rest of your life. Make sure you take care of them. This is another reason why I love to share natural remedies with others. If you can use a natural remedy to help with the health and care of your body instead of using harsh chemicals, you will find they are powerful and gentle.

Have you tried any of the above home remedies for cavities or tooth decay? Did you find that you prefer a certain method over another or did you use the home remedy for your child or children? Let us know about your experience because after all, sharing is caring!
