Can a Cracked Tooth Cause High Blood Pressure? What to Know

Why pain can push your blood pressure up

Pain is a stress signal. The body responds with adrenaline, the heart works a little harder, and blood pressure rises. A cracked tooth that zings every time you bite or drink something cold can do this repeatedly through the day. So can a night of not sleeping because of it.

The rise is temporary. Once the pain is controlled, the reading usually comes back to where it normally sits. If it does not, the tooth was not the cause, and the reading belongs to your doctor.

What a cracked tooth does not do

A crack in the enamel or the root does not change your blood vessels, your kidneys or your heart. It will not turn a normal blood pressure into a high one for good. Anyone who tells you the tooth is the reason you need medication has skipped a step.

A cracked tooth is much more likely to cause a sore jaw or a headache than anything in the chest. If the crack reaches the nerve and the tooth gets infected, the picture is different, and we cover that in cracked tooth: signs, types and whether it can be saved.

The link that does exist: long-term mouth infection

There is research linking long-standing gum disease and chronic infection in the mouth with a higher risk of heart and blood vessel problems. It is an association, not proof that one causes the other, and it is about months and years of untreated infection, not a fresh crack. We go through it in gum disease and heart health. A tooth that cracked, was left, and slowly became infected belongs in that conversation. A tooth that cracked last Tuesday does not.

When a high reading means hospital, not a dentist

Go to an emergency room, and do not come to us first, if a high blood pressure reading comes with any of these:

• Chest pain or pressure
• A sudden, severe headache
• Changes in vision, or trouble speaking
• Weakness or numbness on one side
• Shortness of breath

Those are medical emergencies whatever the tooth is doing. Treat the reading first and the crack second. Our guide to the emergency room versus the dentist for tooth pain covers the other side of that decision.

What to tell us if you have high blood pressure

If you take blood pressure medication, tell us before we start, and bring the list. It matters for two reasons. Some medicines affect bleeding and healing, and some local anaesthetics contain a small amount of adrenaline (epinephrine), which we dose with your blood pressure in mind. We can usually adjust for it. We cannot adjust for something we were not told.

If the reading is very high on the day, we may ask you to see your doctor before any longer treatment. That is not us avoiding the tooth. It is the order the problems should be done in. The American Dental Association's page on cracked teeth explains how cracks are classified, and the American Association of Endodontists has a plain guide to cracked teeth as a second source.

Fixing the crack so the pain stops

The way to take the tooth out of the blood pressure question is to treat it. Depending on how deep the crack goes, that can mean a filling or bonding, a crown to hold the tooth together, a root canal if the nerve is damaged, or an extraction if the crack runs below the gum. We examine it, take an X-ray and explain which of those applies before doing anything. If you want to know how long a crack can wait, read how long you can safely wait to treat it.

If it flares up late in the week in Beit Shemesh

Our clinic at Harav Kook 28/1 is open Sunday to Thursday 8:00 to 20:00 and Friday 9:00 to 17:00, and Shabbat is for genuine emergencies only. A cracked tooth that starts hurting on Thursday night is a worse problem than the same one on Sunday morning, because the weekend is long and the pain does not keep office hours. Same-day appointments are possible at the Beit Shemesh clinic. Dr. Joel is USA-trained and treats in English and Hebrew, so you can describe the pain and the blood pressure medication in whichever language is easier.
