A toothache may cause full, sharp, or throbbing pain. As a result, it can be hard to chew, sleep, concentrate, or talk. Fortunately, by understanding the causes, you can ensure that the problem is properly treated at home or by a dentist. Here’s what you need to know. 

What Causes Toothaches? 

1. Cavity

A cavity forms when decay eats away at the enamel, forming a hole. While there might not be any symptoms at first, you’ll notice pain and sensitivity over time, especially as the decay makes it’s way to the nerves below the teeth. Never ignore the pain, as it will only get worse, making it difficult to function. In some cases, you’ll need a root canal. A dentist can address the problem early on and prevent it from worsening by drilling away at the decay and putting in fillings. 

2. Exercise

Researchers have suggested that exercising causes dry mouth, which is when you lack saliva. In this type of environment, bacteria flourishes, leading to decay. To prevent this issue, hydrate during and after exercise, especially when you’re sweating heavily. 

3. Grinding

Also known as bruxism, grinding can cause aches in the teeth and pain in the jaw, neck, and mouth muscles. It can also lead to tooth fractures, which can be painful when biting hard foods or drinking hot or cold beverages. To prevent this issue, talk to your dentist about getting a custom mouthguard. It’ll need to be worn when playing sports, exercising, and sleeping.

You may also be clenching or grinding during the day if you’re stressed or anxious. To relax, practice deep-breathing, massage your face muscles, and reduce caffeine intake.
