Why Does the Dentist Take Blood Pressure?

With routine dental cleanings being more common than yearly physicals at the doctor for many people, dental visits offer an opportunity to monitor blood pressure and promote well-being.

High blood pressure, or hypertension, is the “silent killer”. About 30% of Americans suffer from hypertension, which frequently remains undiagnosed because it usually has no symptoms.

Why Does the Dentist Take Blood Pressure?

Beyond this added benefit, there are 3 main reasons your dentist should be taking your blood pressure regularly:

  1. Local anaesthetics containing Epinephrine
  2. Dental anxiety and phobia
  3. Discomfort affecting bodily response

 We’ll further elaborate on this below.

Local anaesthetics contain epinephrine 

Local anaesthetics contain epinephrin, raising blood pressure to help the body react to life-threatening circumstances.

Your blood pressure could go up if a dentist applies an epinephrine-containing local anaesthetic without checking your blood pressure, you could end up in danger of a medical disaster. Individuals with high blood pressure frequently are unaware of their condition and do not exhibit any symptoms.

To prevent these potential health issues, Regular dental check-ups are vital.

Dental anxiety and dental phobia  

Many people suffer from dental anxiety and fear of the dentist, When a dentist is taking your blood pressure while you are in the dentist’s chair, they can use that information to create a baseline of your health or to identify any prehypertensive or hypertensive readings that should signal you to see your doctor. 

Confirming that your blood pressure is normal and healthy helps the dentist be aware of any potential hazards linked with treatment, as anxiety and fear can elevate blood pressure.

Discomfort may affect a body’s reaction
