Why does toothpaste for sensitive teeth say to use it for only a month?

Asked by MissAnthrope (21460points) April 19th, 2010

I’ve used two different kinds in the past year and they both instruct to not use more than 30 days (or as instructed by a dentist). When I stop using them, my teeth get sensitive again, so what is it about this toothpaste that I shouldn’t use it for more than a month?

My understanding is that that statement is just to cover their collective ass in case you have a more serious problem that you didn’t get checked out by your dentist. I have been using Sensodyne for years w/no problem. (Antacids have a similar type warning.) The key is “or as instructed by a dentist”. Sample dialogue:
You: My teeth hurt, is there something wrong?
Dentist: Everything looks fine, nothing shows on x-ray, etc etc
You: So can I keep using this toothpaste?
Dentist: Sure!
:-D

Awesome, thanks. I’ve found a toothpaste that works really well for me in terms of helping with sensitivity and I want to use it all the time. I just couldn’t figure out why I wasn’t supposed to use it for more than a month.

This reminds me of a great old joke, if I can get it right…

A man develops a lesion on his penis, and understandably concerned about that, he goes to see his doctor the next morning. His doctor examines him and reports, “I’m afraid I have some bad news for you. That’s a very aggressive infection, and the only way that we can save your life involves amputating your penis. We need to have you in surgery this afternoon.”

The upset patient says that he wants a second opinion, and right away goes to see another doctor that the first one refers him to. The second doctor concurs with the first, and also agrees that the operation has to take place immediately. As a last resort, the patient decides to consult a Chinese herbalist that he’s heard about, and does that next.

The herbalist examines the problem and reassures the man that he can handle this. He gives the man a collection of herbs and ointments, with clear instructions on when and how to apply each. Completely relieved, the man explains to the herbalist. “Can you imagine that the Western doctors I saw this morning thought that I needed an operation to have Ol’ Hoss amputated?”

The herbalist cackles with laughter, “No, that not need. You use medicines I gave, and in two-three weeks it shrivel up and fall off all by self.”
