When tooth decay begins it doesn’t mean you have a cavity right away. Tooth decay happens in stages and progresses when your teeth are continually exposed to acids produced by oral bacteria. Over time, frequent exposure to these acidic byproducts erodes the minerals in your teeth which leads to decay and cavities. There are five stages of tooth decay that contribute to the development of a cavity:
1. Enamel Lesion: The first stage of tooth decay occurs when spots or lesions (typically white or light brown) appear on the tooth’s surface or enamel. This discoloration is a sign of demineralization. It is possible to remineralize the teeth and stop the decay from progressing into a cavity.
2. Enamel Decay: The second stage of decay happens when the enamel continues to break down. At this stage, holes (cavities) can form in your teeth.
3. Dentin Decay: The third stage of tooth decay is when it reaches the layer beneath the enamel known as dentin. The cavity will likely be painful as it is closer to the nerves or root of the tooth.
4. Pulp Decay: This major stage of decay is when the cavity has reached the pulp, the innermost layer of your tooth beneath the dentin. It contains the nerves and blood vessels that provide nutrients to the tooth. Once the pulp has been reached, it can cause a tooth ache and tooth is at risk.
5. Tooth Abscess: The final stage of decay occurs when the bacteria inside the cavity spreads beneath the pulp and forms a pocket of pus. Most times, the infection is extremely painful. Symptoms of tooth abscess vary according to the Mayo Clinic and may result in fever and facial swelling.
Not all tooth decay is created equal, according to The Journal of the American Dental Association (JADA). If you’re hoping to avoid a filling there are a few less invasive options your dentist can use if the decay is caught early in its development. When tooth decay first begins it can look brown or white where the enamel is softening. Topical fluoride treatments and sealants may be your best tool to prevent the cavity from forming and avoid a filling.
Cavities need to be filled. Luckily, there are more types of fillings for teeth than ever before. They vary in complexity and material, from amalgam to composites, or gold and porcelain. There are benefits and drawbacks to each type, such as changing color, longevity, durability and expense. If you’re not able to catch the tooth decay early enough, your dentist will help you determine the best filling type or treatment plan for your cavity.
Regular dental checkups are your best defense to spot tooth decay as early as possible so that non-drilling options are still in your scope of treatment. Remember to brush with fluoride toothpaste after eating or drinking. If your dentist believes you’re at a high risk for decay or cavities, a mouth rinse may also be recommended. Just be aware that being proactive is always best. Use good oral hygiene and keep an open conversation going with your dentist, and hopefully you can keep those cavities at bay.
