Weirdly, chewing on the other side after a root canal can make your jaw sore

Here’s something I didn’t expect: after my root canal, I was so paranoid about hurting the tooth that I chewed exclusively on the opposite side for like two weeks. Turns out, that can actually make your jaw ache, and even mess with your bite a bit if you keep it up too long. My dentist said it’s pretty common because people are nervous about using the treated tooth, but apparently gentle chewing on both sides actually helps your mouth get back to normal faster.

Also, I learned that it’s normal for the tooth to feel kinda “different” for a while—like not painful, just a little off—because the nerve’s gone. It freaked me out at first but now I barely notice it.

Anyone else have weird after-effects like this? Or tips for getting comfortable chewing again?

I totally get where you're coming from. After my root canal, I was super cautious and kept all my chewing to the left side for a while. Eventually, my jaw started feeling stiff and almost tired, which honestly made me more anxious because I thought something else was wrong. My orthodontist actually pointed out that when you favor one side too much, your muscles can get out of whack and it throws your bite off a bit—kind of like limping on one leg for too long.

What helped me was slowly introducing soft foods on the treated side—stuff like scrambled eggs or noodles—just to get used to using both sides again without freaking myself out. It felt weird at first, like you said, but after a few days it got easier. I still catch myself babying that tooth sometimes, but it’s mostly back to normal now.

Honestly, I think the “off” feeling is just part of the process. As long as there’s no pain or swelling, my dentist said it’s all good. The mental part is tougher than the physical healing sometimes...

I can totally relate to that “something else is wrong” spiral. After my root canal, I got so paranoid about every weird twinge or click in my jaw. I didn’t realize how lopsided my chewing habits had become until I tried eating a sandwich and it felt like one side of my face was doing all the heavy lifting. It’s wild how fast your muscles notice when things are out of balance. Soft foods were my go-to too—mashed potatoes became my best friend for a week. It’s funny how much of the recovery is just convincing yourself it’s okay to trust your mouth again...

- Jaw stiffness after switching chewing sides is super common—your muscles just aren’t used to working that way.
- Anxiety definitely ramps up when you notice new sensations, but most of the time it’s just your body adjusting.
- I’ve had the same thing happen after dental work. It usually settles down in a week or so, especially if you stick to softer foods and don’t push it.
- If anything feels sharp or gets worse, that’s when I’d check in with your dentist, but mild soreness is pretty normal.
- Hang in there... it really does get easier once your mouth figures out the new routine.
