Can brushing your teeth cause a heart attack, or is it just a coincidence?
Wow! I brush my teeth regularly. What's going on? Is this dangerous and should I be more careful?

Most likely, it's just a coincidence, but there's one real mechanism worth paying attention to - gum inflammation and bacterial infections in your mouth. If you have chronic inflammation or advanced tooth decay, microbes can enter your bloodstream and cause systemic inflammation. This does genuinely increase the risk of cardiovascular complications, but the process develops over years, not during a single cleaning. The tooth cleaning procedure itself - whether at home or at the dentist - isn't a cause for a heart attack.
It's different if we're talking about dental work against the backdrop of existing heart problems. Stress, adrenaline, and manipulation can trigger an exacerbation, but again, this isn't a typical scenario for regular oral hygiene. If you're concerned about your heart health, see a cardiologist and tell them what happened - the doctor will figure out whether it was related to your teeth or just a coincidence in timing.
And anyway, keep your teeth in good shape: go to the dentist, brush properly. Good oral health is one of those simple things that really does work in favor of your overall health.
A direct link between tooth brushing itself and a heart attack is coincidence. The previous answer is right: neglected cavities and gum inflammation really are connected to heart problems through infection and chronic inflammation. So tooth brushing is prevention, not a risk. You shouldn't worry about the brushing itself, but about your overall oral health.
The main thing is definitely not to stop brushing your teeth! It's not the cause. But if you have heart problems or you're at risk, it makes sense to see a dentist and make sure your gums are healthy - inflammation in the mouth can actually indirectly affect heart health through your overall vessel condition and immune system. Most likely what happened in your case was just a coincidence, but it's a good reason to get your teeth checked and everything else looked at!
Brushing your teeth with a toothbrush definitely doesn't cause a heart attack, but there's a nuance people tend to forget: if you already have heart instability or you're in a risk group, a sudden spike in blood pressure - say, from pain when brushing inflamed gums or from stress - can trigger one right at that moment. Plus, you're right about chronic mouth infections: they really are linked to blood vessel inflammation. Bottom line: don't be afraid to brush your teeth, but if you start noticing chest pain during oral hygiene or dental visits, that's a reason to tell your cardiologist about your heart problems in advance.
Did you happen to have any heart or blood pressure issues before this?
Anyway, the actual mechanical brushing itself is a completely safe procedure, and you definitely shouldn't give it up. What can actually be dangerous is hidden gum problems or cavities that cause chronic inflammation. It really does affect your blood vessels and can worsen heart problems if you already have them.
If the heart attack happened right during brushing, it was most likely a pre-existing condition rather than the cause. But it makes sense to see a cardiologist and a dentist - check if something's been going untreated with your teeth and whether your gums need treatment. Even a routine cleaning by a hygienist when there's inflammation can cause a blood pressure spike, and if your heart's already on edge, that could trigger problems.

No, I didn't have any heart problems before. It was just a coincidence timing-wise - I felt unwell during brushing. Thanks for the explanation about gum inflammation, I'll definitely go see a doctor.
