7 Signs You Might Have a Deep Cavity

7 Signs You Might Have a Deep Cavity


7 Signs You Might Have a Deep Cavity

According to a 2019 report by The Centers For Disease Control and Prevention, 90% of adults in the United States have had a cavity. The CDC also states that 1 in 2 (26%) of adults in the US have untreated tooth decay. Leaving tooth decay untreated can lead to a deep cavity.

What is a Cavity?

A cavity — or tooth decay, as it is also known — is a hole in the enamel of a tooth caused by your teeth being attacked by sugars and acids. Cavities start off small and become bigger the longer they are left untreated.

Signs You Have a Deep Cavity

Unlike small surface cavities, deep cavities can cause a lot of problems and pain if left untreated. Here are seven signs you could have a deep cavity.

1. Unexplained Pain 

You may have a toothache or spontaneous pain that can not be explained. The pain will likely happen without any warning.

2. Sensitivity 

Pain when eating or drinking hot, cold or sweet things could be a sign of a deep cavity. You may also feel that the tooth (or teeth) are generally very sensitive, and it may also be painful when you bite down or chew.

3. Bad Breath/Taste in Your Mouth 

Bad breath, a foul taste in your mouth or tasting copper could be a sign of decay. We all have morning breath, but if your bad breath is constant, then it’s time to be checked out. Your breath on the whole should be quite neutral. The copper taste could be from blood in your mouth. All of these can be a sign of a deep cavity and possibly gum disease, which will also need treatment.

4. Puss/Lump on Your Gum 

Puss or a lump on your gum could be a sign of an abscess — an infection caused by deep decay. If you are experiencing difficulty breathing, bleeding, pain or facial swelling, this is classified as a dental emergency and you should seek help immediately.

5. Broken Teeth 

Cavities will weaken your teeth. The longer they are left untreated, the weaker the teeth become. Eventually, the teeth may fracture and break completely. If your tooth is broken, it has likely been caused by a deep cavity. The sooner you seek treatment, the better it is for the tooth’s prognosis.

6. Discolored Teeth 

Black, brown or gray spots on the teeth are a sign of cavities. It could also just be staining, but staining can lead to decay. So, getting the teeth checked if you see any discoloration is important.

7. Visible Holes 

Noticeable holes or pits in your teeth may be a sign of decay. The bigger the holes are, the more likely it is that they are deep cavities.

Ways to Prevent Deep Cavities
