What Does Tooth Decay Look Like?

Tooth decay, also known as dental caries or cavities, is a common problem that affects people of all ages and is caused by the build-up of plaque on the teeth. Plaque contains harmful bacteria that feed on sugars from the foods we eat and produce acids that erode our tooth enamel. If left untreated, tooth decay can lead to pain, infection, and even tooth loss.

Tooth decay usually appears as discoloured spots on teeth, ranging from white to brown or black. In the early stages, decay may appear as small white patches due to enamel demineralization. As it progresses, these spots can darken and form small pits or holes. 

Advanced decay leads to larger cavities and noticeable damage, and the affected teeth may become sensitive to hot, cold, or sweet foods and drinks.

Signs & Symptoms

The early stages of tooth decay often go unnoticed, as they may not cause significant or detectable symptoms. However, as tooth decay progresses, you may begin to experience a variety of signs that warrant attention. These can include:

  • Tooth sensitivity: You might feel pain or discomfort when consuming hot or cold beverages and foods. This sensitivity can occur as the protective enamel on your teeth begins to wear away, exposing the underlying dentin, which is more sensitive to temperature changes.
  • Toothache: This can manifest as either a dull, lingering ache or sharp, intense pain that can sometimes escalate to severe discomfort. Toothaches may be triggered by pressure from chewing, or may even present as spontaneous pain that occurs without any apparent cause.
  • Visible discoloration: As tooth decay develops, you may notice changes in the colour of your teeth. This can manifest as white spots, which indicate demineralization, or in the case of more advanced decay, as brown or black spots on the surface of the teeth.
  • Bad breath: The bacteria responsible for tooth decay produce foul-smelling gases as they metabolize sugars and carbohydrates. These gases can lead to persistent bad breath (halitosis), which can be embarrassing and may indicate more significant oral health issues.
  • Unpleasant taste in the mouth: You might also experience a metallic or bitter taste in your mouth. This is the result of decaying teeth or the bacteria involved in the decay process. The unpleasant taste can linger, and may even affect your appetite.

If you notice any of these symptoms, it’s crucial to schedule an appointment with your dentist for a thorough evaluation and appropriate treatment. Your dentist will be able to identify and diagnose tooth decay through a visual examination, which may include using tools to detect soft spots on your teeth and potentially taking X-rays to assess the extent of the decay.

Preventing Tooth Decay

The good news is that tooth decay is preventable with good oral hygiene habits and regular dental visits. Here are some tips to help prevent tooth decay:

  • Brush your teeth twice a day with fluoride toothpaste.
  • Floss daily to remove plaque and food particles from between your teeth.
  • Limit sugary and acidic foods and drinks.
  • Drink plenty of water throughout the day to help rinse away bacteria and food debris.
  • Chew sugar-free gum after meals to stimulate saliva production, which helps neutralize acid in the mouth.

It’s also important to visit your dentist regularly for cleanings and check-ups. They can remove any built-up plaque or tartar that may contribute to tooth decay, as well as identify any potential issues before these become more serious.

Professional Treatments for Tooth Decay

If you do develop tooth decay, your dentist may recommend one of the following treatments:

  • Fillings: This is the most common treatment for tooth decay. The decayed portion of the tooth is removed and replaced with a filling made of composite resin, amalgam, or other materials.
  • Crowns: If the decay has spread to a larger area of the tooth, or if there is significant damage, a crown may be necessary. This involves placing a cap over the remaining part of the tooth to protect it and restore its function.
  • Root canal therapy: If the decay reaches into the pulp (the innermost part of the tooth, containing nerves and blood vessels), it can cause a toothache and infection. In such cases, a root canal may be needed to remove the infected tissue and save the tooth.
  • Tooth extraction: In severe cases where the decay is too extensive or if there is an abscess (a pus-filled pocket), the tooth may need to be extracted. This is usually a last resort when all other options have been exhausted.
