Toothache vs TMJ Pain: How to Tell the Difference and When to See a Dentist

Toothache vs TMJ pain is a question of source: a toothache starts in one tooth, while TMJ pain starts in the jaw joint or in the muscles that move the jaw. The overlap is real. A sore joint can make several teeth ache, and a damaged tooth can make the jaw muscle tighten around it. Sorting the two starts with where you can point, what sets the pain off, and what else is happening in the face.

White tooth model, dental instruments, and money illustrating the cost of root canal treatment in Ontario

How Much Does a Root Canal Cost in Ontario?

How much a root canal costs in Ontario depends on the number of canals in the tooth, whether those canals have been treated before, and any other work the tooth still needs. A front tooth with one canal takes less time than a molar with three or four. The fee for cleaning and filling the canals leaves out the crown, the post, and any sedation. Those are separate lines.

Bleeding gums when you brush are inflamed. That is what the bleeding means, and it is almost never a sign that you are brushing too hard. Healthy gum tissue doesn't bleed when a soft brush passes over it, just as healthy skin doesn't bleed when you wash it. In most cases, plaque along the gumline is the cause; the condition is early gingivitis, and it can be completely reversible within one to two weeks with proper cleaning. If the bleeding persists after two weeks of genuinely good home care, the problem has moved past what brushing can fix and needs to be addressed. The distinction between those two situations is what this article is about.

Dentist examining a patient's mouth for a cold sore or canker sore

Cold Sore or Canker Sore? How to Tell Them Apart and What to Do About Each

A canker sore is a small ulcer that forms inside your mouth, is not contagious, and is not caused by a virus, while a cold sore is a cluster of blisters that appears outside your mouth, usually on or near the lips, is very contagious, and is caused by the herpes simplex virus. Both are painful, both usually heal on their own within one to two weeks, and both are common. But because they have different causes and one can spread to other people, telling them apart changes how you treat them, how careful you need to be around others, and when it is worth having a dentist take a look.
