Tooth Decay Treatment in Claremont

Tooth decay, also known as dental caries, is a bacterial infection that damages the structure of our teeth

It starts with our natural bacteria producing acid that erodes the protective enamel and dentin. Left unchecked, this can lead to the formation of painful cavities, sensitivity, and even the devastating loss of teeth.

Prevention & Treatment

Tooth Decay Treatment

Tooth decay or dental caries can be prevented by periodic professional fluoride treatment and placing fissure sealant wherever indicated. Initial caries, also called incipient caries can be reversed by appropriate oral hygiene measures including flossing, improvement in diet, use of fissure seals and fluoride. More advanced caries can be treated with composite or ceramics, fillings.

Extensive caries involving the pulp may require root canal treatment and a crown. If the tooth is non restorable, extraction and prosthetic replacement may be needed.

Causes & Risk Factors

Diet is the primary perpetrator behind the destruction of your teeth, causing the formation of cavities and tooth decay. The bacteria that resides in your mouth feeds on sugars from your diet and releases acid as a byproduct. When this acid comes into contact with the teeth, it can dissolve the minerals in the enamel and dentin, leading to the formation of a cavity. The process of tooth decay can be exacerbated by poor oral hygiene, a diet high in sugar and carbohydrates, and a lack of fluoride, among other factors.


Foods that are sticky and sugary such as ice cream and lollies are more likely to cause decay as they contain high sugar content and stick to your teeth. Avoid eating and drinking a lot of foods and drinks such as ice cream, soda, lollies, dried fruit, cookies, mints and other sticky or sugary foods.


Additionally, the more you snack, the more fuel you are giving the bacteria to produce more acid.

Poor oral hygiene

If you don’t clean your teeth and floss well, plaque will form around your teeth causing tooth decay and tooth

Lack of fluoride

Fluoride helps prevent tooth cavities and tooth decay. It is often an ingredient used in toothpaste and mouth rinse. If the products you use don’t provide enough fluoride, your dentist can do a fluoride treatment which will boost the fluoride needed in your enamel. At your regular check up, your dentist will be able to identify signs of tooth decay and help determine the root of the problem.

Dry mouth

Dry mouth is caused by the lack of saliva production in your mouth. Saliva helps prevent tooth decay by washing away the plaque from your teeth. Help to prevent cavities and dry mouth by drinking plenty of water.


Heartburn causes your stomach acid to come up into your mouth wearing away the enamel of your teeth causing significant damage. This exposes more of the dentin, enabling attacks from the bacteria resulting in tooth decay and/or a tooth cavity.

Frequently Asked Questions


Generally, we see 5 stages of tooth decay here at  Ashton Avenue Dental.

  1. Initial. The acid produced by bacteria in your mouth begins to erode the enamel of your teeth. You may see small pits or white spots on the surface of your teeth.
  2. Early. The decay has now progressed deeper, into the dentin of your tooth. At this stage, you will notice small cavities or holes in your teeth.
  3. Moderate. This stage is where the decay has progressed even further into your tooth, reaching what’s known as the pulp chamber. You may notice tooth sensitivity to hot and cold temperatures, and the cavities or holes will be larger.
  4. Advanced. The decay has reached the root, and you may now have an infection or abscess. You may be in pain, and in order to save the tooth, your dentist might suggest root canal treatment.
  5. Severe. Unfortunately, the level of decay has rendered the tooth non-restorable and will need to be extracted.
Yes! In the earlier stages of tooth decay, it can be reversed by removing plaque and bacteria build up, and then restoring the lost tooth structure with fluoride or remineralising agents.

Yes! Tooth decay can lead to halitosis, otherwise known as bad breath. The bacteria that cause tooth decay and tooth cavities in your mouth can produce a foul odour. Furthermore, if your tooth decay has resulted in infection or abscesses, the likelihood of having bad breath is even higher. If you have bad breath and suspect tooth decay, see your dentist at Ashton Avenue Dental for treatment.
