How Dental Fillings Can Prevent Cavities

General Dentist Newtown, CT

Most people think of dental fillings as a way to treat cavities, but they can also help to prevent them. Tooth decay is caused by acids eating away at teeth. Fillings are one of the popular ways to close up the holes created by decay. The acids that damage teeth are made by bacteria in the mouth that convert sugars in the small bits of food left on teeth after meals into acid.

Preventing cavities with dental fillings

Tooth decay often starts as a white spot that indicates a tooth is being demineralized. This stage of decay can easily be reversed with a fluoride treatment. Leaving it unaddressed leads to a cavity eventually forming on the tooth. The cavity will grow bigger if not treated until it opens up the pulp chamber – leaving the tooth vulnerable to infection – or leads to the tooth breaking apart. The rate at which the decay progresses increases once it gets past the enamel since the next layer, called the dentin, is not as durable as enamel.

Tooth decay is one of those dental issues most people will deal with at some point in their lives. It can lead to toothaches, infection, and the loss of teeth. Fortunately, tooth decay is preventable, and simple things like brushing and flossing go a long way when it comes to protecting teeth against decay. People who fail to take good care of their teeth are more likely to deal with tooth decay.

How dental fillings help

Once a tooth’s structures begin to succumb to tooth decay, dental fillings can be used to close up the hole. The process often starts with the dentist administering a shot of a local anesthetic so the patient does not feel any pain as the dentist works.

The dentist removes rotting teeth material from the tooth and uses dental filling to close up the space. Fillings have a semi-solid consistency when applied, but the substance hardens up when it makes contact with air, saliva, or a curing light. Closing up the hole created by decay prevents acids from eating away at the weaker dentin. The filling serves as artificial enamel, protecting the more delicate inner layers of the tooth.

Dental fillings also help to strengthen teeth that have been damaged by decay. It can help to prevent the tooth from chipping, cracking, or breaking due to biting forces. Chipped, broken, or cracked teeth are more susceptible to tooth decay than teeth that have been repaired with filling.

Address tooth decay with fillings

Tooth decay is one of the most common dental issues, but it is also a very preventable problem. Keeping teeth decay-free starts with good oral hygiene and getting cavities fixed with a fluoride treatment or fillings as soon as they are detected.

Leaving cavities untreated can lead to excruciating toothaches, infection, or the loss of a tooth. All that can be avoided by sealing the cavity with dental fillings. Give us a call or stop by our Newtown clinic to set up an appointment with our dentist.
