5 Most Common Signs of a Dying Tooth

Dental hygiene is a crucial part of our overall health. When we lack in this field, it may damage our bodies and well-being. We should always make sure to keep up a constant, efficient routine to manage our oral cleanliness. Our teeth help us with mastication so we can digest our food more easily and safely. Failure to take care of our teeth could result in them getting damaged. Sometimes, the tooth can repair itself, but it could die if the damage is irrecoverable.

The pulp, soft tissue in the centre of our teeth, contains blood vessels and nerve tissues. When the pulp is unharmed, it allows these elements to keep our teeth alive. If our teeth get damaged or are weak enough, the bacteria in our mouths can eat away at the enamel and reach the pulp. This then creates an infection that spreads and begins killing the tooth. These openings could result from the cracking of a tooth or through deep cavities.

The reasons for dying teeth could expand beyond our reach as well. While brushing and flossing are some habits we can depend on ourselves for, external conflicts that we do not account for could catch us by surprise. The process of your teeth dying could also occur over days, weeks, or months, so the signs may not always be very apparent. However, there are ways to identify the problem.

Here are five signs of a dying tooth:

Sign of a dying tooth #1: Pain

Have you ever noticed a pain in your tooth when eating something, or even randomly? If so, then it could be a case of a dying tooth. The interior accumulation of bacteria forms a cavity which creates uncomfortable pressure.

The infections affecting the pulp and the nerve endings of its nerves cause this pain, which could either be mild or severe. Consult an emergency dentist Mississauga if the pain becomes unbearable.

Sign of a dying tooth #2: Over-sensitivity

Another sign of a dying tooth is if drinking a hot or cold beverage creates a painful sensation. The over-sensitivity is another cause of the infection of the pulp’s nerve endings due to its exposure.

Sign of a dying tooth #3: Discolouration

Like all dying things, teeth also lose colour as they lose their life. During the process, the lack of blood supply depletes the white colour from your tooth. If you observe your tooth turning into a grey, black, yellow, or brown colour, it will most likely die. The discolouration will intensify as time passes, and the red blood cells die.

Sign of a dying tooth #4: Bad breath and taste

While bad breath and taste in your mouth could be normal, it could also indicate a dying tooth. If the smell and taste are still there after you have taken measurements to make sure that it should lessen, then the source may be the decay of your teeth.

Sign of a dying tooth #5: Swelling gums

When your tooth decays, the bacteria causing the infection could spread to your gums. This causes the gums to swell or may even create pimples on them. This may also be painful and create an irritable feeling in your mouth.

How to treat a dying tooth

So, what should you do if you notice any of these signs? Go to your dentist immediately. The more time you waste not seeking professional help, the worse the infection gets, and the less likely the tooth can be saved. If caught in time, the tooth may be salvageable.

Root canal

A root canal may be suggested, where the pulp is removed, and the gap is cleared, filled and sealed. This strategy allows for the tooth to be saved.


However, if the tooth is beyond saving, it must be extracted. Following the extraction, an implant may replace the missing tooth.

Calm the irritation

Throughout this process, try not to aggravate your dying or recovering tooth. If your gums are swollen, apply anti-inflammatory medication to them to help the swelling decrease. Avoid extremely hot drinks and solid foods. The pressure and sensitivity will get on its nerves.

A good routine

Ensure you stick to a nutritious diet and strict oral hygiene routine. Steer clear of sugary foods as much as possible. Brush your teeth twice a day and floss at least once. Accompany the end of every meal with a glass of water to wash away any bacteria and food particles stuck between your teeth.


A mouth guard may come in handy if you play any kind of sports that could result in something hitting your face. It covers your teeth and gums to protect them in case of injuries.
