Tooth decay is a common oral health problem that affects people of all ages. It is caused by the accumulation of bacteria on the teeth, which produce acids that break down the tooth’s enamel and create holes, or cavities. If left untreated, tooth decay can progress through various stages, each with its own symptoms and treatment options. This article will discuss the stages of tooth decay and how to prevent and treat them.
What are the Stages of Tooth Decay
Stage 1: Demineralization
The first stage of tooth decay is demineralization and creation of an incipient lesion. Put simply, demineralization is the loss of minerals (calcium and phosphate) in your teeth. This occurs when the bacteria in plaque, primarily streptococcus mutans, produce acids that dissolve the minerals in the enamel (the outer layer of your tooth), causing it to weaken and break down. This is the beginning of a cavity.
At this stage, the decay may not be noticeable on x-rays and may even be reversible with proper oral hygiene and remineralization techniques. If you look closely, it may appear as a chalky white rough spot on the tooth, which is an indication of enamel loss. If left untreated, the decay will progress to the next stage. We have a full article on how to reverse a cavity for those looking to treat demineralization.
Stage 2: Enamel Decay
The second stage of tooth decay is enamel decay. At this stage, the weakened enamel collapses due to the actions of acids and enzymes in the mouth, forming an irreversible cavity. The cavity is visible on x-rays as a small black line in the enamel. If probed with a dental instrument, the decay will feel soft and sticky.
Stage 3: Dentin Decay
The third stage of tooth decay is dentin decay. In this stage, the bacteria begin to attack the layer beneath the enamel, known as dentin. As the dentin breaks down, the tooth may become sensitive to hot and cold temperatures and may even cause pain. Similar to enamel decay, dentin decay can be seen on x-rays, are typically light brown in colour to the eye, and sticky when probed.
At this stage, the decay is more advanced and may require a filling or a crown to restore the tooth. A crown will typically be used if the damage is too severe for a simple filling (greater than 40% of the tooth).
Stage 4: Pulp Decay
The fourth stage of tooth decay is pulp decay. In this stage, the bacteria reach the tooth’s pulp, which contains blood vessels, teeth nerves, and connective tissue. When the pulp becomes infected, it can cause severe pain, swelling, and lead to an abscess.
At this stage, the decay may be treated with root canal therapy, in which the infected pulp is removed, and the tooth is sealed to prevent further infection. Another possible option is considering extraction vs a root canal; however, dentists try to save the original tooth if possible. If left untreated, the decay will progress to the next and final stage.
Stage 5: Tooth Abscess
The final stage of tooth decay is tooth abscess. In this stage, the infection spreads to the root of the tooth, causing a severe abscess. The abscess can cause severe pain, swelling, and fever and can even spread to other areas of the body if not treated promptly. At this stage, the decay may be treated with antibiotics and tooth extraction.
The Sooner The Treatment, the Better the Outcome
It is important to remember that the sooner you get treatment for tooth decay, the better your outcome will be. Ideally, you want to prevent tooth decay before it starts by practicing good oral hygiene habits and regularly visiting your dentist for check-ups and cleanings. However, if you do begin to experience the stages of tooth decay, it is important to seek treatment as soon as possible. Early diagnosis and intervention can help you avoid more invasive treatments and save your tooth. Typically the longer you wait, the more costly the dental procedure is likely to be. It is always best to seek treatment sooner than later!
Conclusion
Overall, tooth decay is a progressive condition that requires prompt treatment to prevent further damage. By understanding the stages of decay, individuals can better understand the severity of their condition and make informed decisions about their oral health.
