Early Signs of Tooth Decay

Hi, I’m Dr Billy Choi, the principal dentist at Precision Dental here at Fortitude Valley in Brisbane.

Last Thursday, I saw one of our new patients, Josie, for a check up and clean. She works in the city, and hasn’t seen a dentist since the beginning of Covid. After reading our Google reviews, she decided to book an appointment with us.

After the treatment, I mentioned to her that I noticed a couple of her back molars were starting to decay. I showed her some photos on the computer screen. She was so surprised, since she didn’t feel any toothache.

During our conversation, she asked me, “Billy, what are the early signs of tooth decay?”

It is a comment question we get from our patients, so I decided to make a quick video sharing with you what I shared with Josie.


The most common sign of tooth decay is sensitivity or pain, mostly to hot and cold drinks or food. It could be just short, sharp sensitivity, or it could be a lingering sensitivity.


The second sign of tooth decay is a hole or cavity in your tooth. Sometimes you can feel it with your tongue, other times, you can visually see a tooth that has gone brown or dark. If this is the case, it is an advanced stage of tooth decay.


The third sign of tooth decay is when a patient complains that they have bad breath. When you have cavities that retain the food particle, and it is decaying in the mouth, it can certainly affect the smell of the breath.
