Hay fever is caused by the immune system overreacting to allergens like airborne pollen, and it can cause a stuffy nose, itchy and runny eyes, and headaches. It can also affect your oral health.
One of the most unpleasant side-effects of hay fever is sinus pain, as your sinuses are hollow spaces just above your upper back teeth and which can soon fill up with mucus. Unfortunately, the pain can spread to your teeth because the buildup of mucus can press on tooth roots. Another unpleasant side-effect is dry mouth and especially if you need to breathe through your mouth instead of your nose during sleep. Mouth breathing quickly dries up saliva which is a natural and protective fluid against cavities and gum disease. Without saliva, bacteria in your mouth will soon multiply, and you could have bad breath. Lastly, hay fever can cause a sore throat because bacteria build up right at the back of the throat.
If you are affected by hay fever, it’s even more important to take good care of your oral health. Make sure you brush your teeth at least twice a day and floss once-a-day to protect your teeth and gums. Any persistent toothache should always be investigated, in case your sinuses aren’t causing it.
