This is a common question since it seems like blood pressure and dentistry are uncorrelated. On the contrary, blood pressure plays a large role in how your dental visit will play out.
Blood pressure readings are important in determining the type of local anesthetic chosen for your dental injection. Your dental professional may opt for an anesthetic without epinephrine if your blood pressure is elevated.
If high blood pressure (hypertension) is detected, your dental professional will let you know and may recommend you see your primary care physician. If it is elevated enough, dental treatment may have to be deferred and a medical consult form may need to be sent to your physician and signed before undergoing any dental treatment to avoid a hypertensive crisis.
