People who have sensitive teeth have to deal with a number of problems. Switching toothbrushes, toothpaste or even changing diet patterns don’t help. Today we talk about some weird health reasons that could trigger teeth sensitivity.
Sinus: People who suffer from sinus getting a dental infection or even suffering from teeth sensitivity is common. This is because the sinus lies close to the floor of the teeth and so a sinus that flares up with a bad cold can lead to a headache, jaw pain or teeth sensitivity. 
Menstruation: Menstruation gingivitis is a common oral problem that women go through but hardly know about it. This happens due to hormonal fluctuations during the course of menstruation or days before you get your period. And if you suffer from this teeth sensitivity might just follow, says Dr Karishma Jaradi, Aesthetic Dentist – Dentzz Dental Care Centres.
Pregnancy: Hormonal fluctuation during pregnancy is common. It does a lot of things to your body and one of them is making your teeth sensitive. I changed three kinds of toothpaste during my second pregnancy and I don’t have a tooth problem otherwise.
Bruxism: People who suffer from bruxism or teeth grinding at night also suffer from teeth sensitivity as it erodes the enamel and makes them susceptible to it .
Stress: Probably stress doesn’t contribute to teeth sensitivity directly but there are studies that say psychological stress appears to contribute to poor oral health systemically in combination with other chronic diseases. Moreover, stress is also a precursor of Bruxism which could make your teeth sensitive .
Cold weather: You might have also noticed it that the cool weathers actually gives your gums an unusual sensation and makes your teeth sensitive during the winter months.
Acid reflux: If you suffer from severe acidity gastric acid will displace saliva easily from tooth surfaces and proteolytic pepsin will remove the protective dental covering. There has been increasing evidence of associations between GERD and tooth erosion has been shown in both animal and human studies. This makes teeth susceptible to sensitivity.
