Tooth Decay
Tooth Decay
Tooth decay is a dental condition that develops over time. It happens when bacteria that live in dental plaque begin to damage the surface of a tooth. Plaque is the thin, sticky film that builds up on teeth during the day, particularly after eating.
When sugary foods or drinks are consumed, the bacteria in plaque use those sugars and produce acid. This acid can slowly weaken the outer layer of the tooth, known as enamel. If this process continues, the enamel may begin to break down, and a small hole can form in the tooth. This is commonly called a cavity.
Tooth decay is one of the more frequently seen dental problems, and it can affect people of all ages. In many cases, the early stages are difficult to notice because there may be little or no discomfort at first. For that reason, routine dental visits are often useful in identifying early changes before they progress further.
At Healthy Smiles, a dental examination usually includes checking the teeth for signs of decay and discussing ways to help maintain long-term oral health.
Risk Factors
Anyone can develop tooth decay, although certain factors can make it more likely.
Limited fluoride exposure
Fluoride helps strengthen the enamel and supports the natural repair process of teeth. It is commonly present in drinking water in many areas and is also found in most toothpastes.
Weaker or chalky enamel
Some teeth form with enamel that is naturally less mineralised. This may appear as chalky white areas or slightly uneven enamel. Teeth with weaker enamel may be more susceptible to damage from acids and bacteria.
Gum recession or exposed tooth roots
When gums recede, the root surface of the tooth may become exposed. This part of the tooth contains dentine, which is softer than enamel and can be affected by acids more easily.
Frequent sugary or acidic foods and drinks
Regular snacking or drinking sugary beverages gives plaque bacteria repeated opportunities to produce acid. Over time, this can increase the likelihood of enamel damage.
Reduced saliva flow
Saliva plays an important role in protecting teeth. It helps wash away food particles and neutralise acids in the mouth. Some medications, health conditions, or dehydration may reduce saliva flow and increase the risk of decay.
Signs and Symptoms of Tooth Decay
In the beginning, tooth decay often develops without noticeable symptoms. As the condition progresses, changes in the tooth may become more apparent.
White or dark spots on the tooth
Early decay can sometimes appear as chalky white areas on the enamel. Over time, these areas may darken or develop into a visible cavity.
Sensitivity
A tooth affected by decay may feel sensitive when eating sweet foods or drinking something very cold or hot.
Food getting caught in the tooth
As a cavity becomes larger, food particles may start to collect in the area. This can sometimes make the tooth feel uncomfortable and may make cleaning more difficult.
Unpleasant taste or breath
Bacteria involved in tooth decay can occasionally contribute to an unpleasant taste in the mouth or ongoing bad breath.
Toothache
If decay reaches deeper parts of the tooth, it may begin to affect the inner tissue. At this stage, the tooth may become painful during eating or when exposed to temperature changes.
Treatment and Prevention
Treatment and Prevention
Supporting a healthy oral environment can help reduce the likelihood of tooth decay. Good daily habits and regular dental care both play a role in maintaining healthy teeth.
Some helpful steps include:
Brushing teeth twice a day using fluoride toothpaste
Cleaning between the teeth with floss or interdental brushes
Attending regular dental check-ups and professional cleans
Limiting the frequency of sugary snacks and drinks
Drinking water regularly throughout the day
Dentists may also discuss preventive approaches such as fluoride applications or fissure sealants in certain situations.
