Maintaining a healthy smile is essential for your overall well-being. At Metropointe Dental, we are here to answer your questions and provide guidance on cavity prevention, tooth decay, and oral health care. In this blog, we’ll explore some common concerns and tips for keeping your teeth in great shape.

What is a cavity?

Cavities are holes that form in your teeth due to progressive tooth decay affecting the hard outer layer known as enamel. Initially, cavities present as white or chalky spots on the surface, indicating areas where enamel has eroded—this marks the first stage of cavity formation. Once the enamel is worn away, cavity-causing bacteria and acids can penetrate to the next layer of the tooth, called dentin. As these bacteria gain access to the dentin, they continue to break down the tooth structure, ultimately leading to the formation of holes called cavities. 

Can tooth decay be reversed?

In the early stages of tooth decay, when white spots appear on the enamel, it is possible to stop or even reverse the decay. During this phase, the enamel can naturally repair itself with the aid of minerals found in saliva and fluoride-containing toothpaste. However, if tooth decay progresses and the enamel is further weakened, leading to the formation of a cavity, the tooth will be permanently damaged and can only be repaired by a dentist.

What can I do to prevent cavities?

Cavities are caused by acidic foods and drinks, sugars, and food debris that bacteria thrive on. As bacteria feed, they form plaque, which can lead to tooth decay and harden into rough deposits that protect bacteria, creating a breeding ground for cavities.

To prevent plaque buildup, we recommend brushing and flossing your teeth twice daily, particularly after consuming sugary treats, sticky foods like gummies or raisins, and acidic drinks such as sodas and coffee. Additionally, increasing saliva production can help rinse away bacteria in the mouth. You can boost saliva by drinking water throughout the day or chewing on sugar-free gum. 

Dental Tip: Visit your dentist for cleanings every six months to help remove hardened plaque and identify areas that need more attention when brushing and flossing.
