So can sinus pressure cause toothaches? The simple answer to this question is yes. Indeed it can, and that answer will surprise many people. However, when you look deeper, there are logical reasons as to why this can happen.
Sinus pressure can occur for a number of reasons. One of the most common reasons is a sinus infection, sometimes called sinusitis. This has a number of impacts including inflammation and pressure. Tooth pain in such a situation is quite common, especially in teeth which are at the back of the top gum and thus nearest the sinus. The teeth become painful because the fluid that builds up in the sinus cavities puts pressure on the upper teeth. The pain can feel like a dull ache or something pressing down on the teeth and can also be noticeable when chewing.
If you are suffering from tooth pain and also have a sinus infection, what is the most effective course of treatment to follow? In most cases, the pain will pass as the sinus infection clears up. However, in extreme cases, a visit to the dentist would be recommended so that the dentist can rule out other issues such as tooth decay or cavities.
Assuming there are no dental issues requiring treatment then the next course of action is to visit your doctor so the sinus infection can be treated. A doctor will normally treat a sinus infection with antibiotics or antihistamines depending on the potential cause. Once the infection has cleared up, then the dental pain will disappear quite quickly. If it doesn’t then a follow up a visit to the dentist may be required. A patient should also ensure that they drink plenty of water as a sinus infection can cause a dry mouth and brush their teeth using a fluoride toothpaste as a dry mouth can increase the risk of dental infection and decay.
