What are the Signs and Symptoms of Tooth Decay?

Experiencing discomfort in your mouth? Tooth decay doesn't play favorites and can sneak up on anyone. At The Warm Smile, your trusted dentist in Melbourne, we’re here to help you recognize the warning signs and take action early.

Here are some symptoms to watch for:

On and Off Toothache

A quick, sharp pain in your tooth can indicate tooth decay. Untreated tooth decay grows over time, causing damage to the internal part of the tooth. If left for too long, it can reach the nerve, turning the pain from intermittent and cold-induced to constant and throbbing, indicating nerve damage and the need for a root canal treatment, which is considerably more expensive than just a filling.

Sensitivity to Sweet, Hot, or Cold

If your teeth protest against that scoop of ice cream or hot coffee, take note. Sensitivity to sweet, hot, or cold foods and drinks is a common symptom of tooth decay. This is why it’s important to have regular check-ups and periodic radiographs, as many times the teeth can look perfect on the outside while hidden cavities are forming between them, only becoming noticeable once they are too big and the tooth breaks.

Visible Pits or Holes

These are areas where the enamel has broken down, and bacteria have made themselves at home. Check your teeth in the mirror regularly for any noticeable pits or holes.

Stains on the Surface

Dark spots or white streaks on your teeth might not just be a matter of pigmentation change. These could indicate areas of decay that need attention. Brown lines and points on your posterior teeth do not necessarily indicate decay; most of the time, these are just pigmentations. It’s important to see a dentist to recognize what is a stain and what is a proper cavity.

Bad Breath or an Unpleasant Taste

Persistent foul taste or bad breath could signal decay. If mouthwash and brushing don’t seem to help, it’s time for a dental check-up.

Don't wait until a minor cavity turns into a major problem. At The Warm Smile, we’re equipped with state-of-the-art technology for early detection and treatment. Whether you need a filling, a crown, or just peace of mind, our team is here to support your dental health journey.
