Tamoxifen and teeth sensitivity...anyone notice an issue?

Was wondering if anyone noticed a change since taking Tamoxifen. I'm on it 6months now. Did no chemo or rads. Had a dental check up and cleaning in January. Just started to notice some sensitivity when biting down and drinking hot/cold sometimes even room temperature water would make my teeth hurt. Thought I was getting a bunch of cavities. My dentist looked around, even took x-rays and nothing. (unless its slightly fractured and will eventually crack(filling)). It's not even one tooth! its a few. Been using Sensodyne Rapid relief toothpaste and Listerine Sensitivity wash. Thinking maybe its from the drying effects of Tamoxifen. Im sure it can have an affect on oral tissues as well.. Maybe Biotene or something of that sort to keep mouth hydrated would work.

Anyone come across same problems while on Tamoxifen? Any relief?

Yes or maybe. I thought I had a couple cavities too but dentist said no. She said I was brushing too hard and damaged some enamel, so I am using Sensodyne as well. I’ve been brushing the same way as long as I can remember so I don’t think it’s just me but with all the treatments and tamoxifen keeping me in early menopause, I can’t say with certainty that this is the cause but a contributing factor sounds reasonable.

Not sensitivity per se, but my gums are really fragile now. Like really fragile. I can't eat things that are hard anymore, like chips or toasted bread. It just rips up my gums. My dentist said I have dry mouth (he says from tamoxifen) and I use Biotene. Can't say it's fixed the problem, but it definitely hasn't made it worse. Sigh. I'm almost 40 and I feel like I have an elderly mouth already. I know I have dry mouth because I wake up with my tongue stuck to my nightguard. Yuck!!! :-)

I feel like this is definitely a side effect that is worth noting. I only began Tamoxifen a week ago, but had instantaneous eye dryness/pain /irritation AND incredible sudden tooth sensitivity. I have never, ever had either problem before. I seem to have also scored some fairly unusual side effects with other treatments. I even went to the optometrist yesterday, but was told everything was perfectly normal. Wondering if there's any point going to the dentist!

I'm a Dental Hygienist. When you are under stress, you will clench your teeth at night. This will cause sensitivity. The stress from cancer is just that kind of stress. Also, if you have changed to a whitening toothpaste, change back. Whiteners tend to make teeth sensitive, too. The sensodyne should help. If it worsens, talk to your dentist about a nightguard. Also, contrary to what someone else posted, fluoride will desensitize teeth. Therefore, if you can get a prescription for Prevident fluoride gel from your dentist, this will also help. This is what i do because i have this problem, too. If you use the Prevident, brush it on and spit it out, but try not to rinse it out too much and go on to bed. That way, it stays on your teeth long enough to work. I hope this helps.
