Hot, Cold or Warm – What Water Temp Do You Use to Brush Your Teeth?

When it comes to brushing your teeth, what's your routine?  I had my mind blown last night and now I'm questioning life.

Last night I had finished brushing my teeth and my boyfriend came in behind me and started brushing his teeth. I was standing in the door talking to him and he looked at me like I was crazy and said, "you brush your teeth with cold water?"  "Uh yes, I brush my teeth with cold water."   I asked him if he used hot water to brush his teeth and he said, "I use warm."  I was like why?   "Why would you brush your teeth with warm/hot water?  That's just weird."  To which he proceeded to tell me, that I was weird for using cold water.

That got me thinking, what temperature of water do people use when brushing their teeth?  Do most use warm/hot water?  Am I in the minority?  Is he in the minority?  What's the right answer here?  My mind literally exploded last night.  I cannot quite fathom that some people use warm water to brush their teeth.  Then again my boyfriend thought I was crazy to use cold water.

This could be a game changer for us, could this be the breaking point in our relationship.  Probably not, but it's fun to tease.  Do me a favor and take the poll.  Am I the crazy cold water user or is he the weirdo warm water user?

From everything I have read, it's the users preference on what temperature of water they use to brush their teeth.

I understand that for people who have really sensitive teeth, cold water wouldn't work, but for some reason the idea of warm water while brushing my teeth grosses me out.

In fact according to a study done for the Indian Journal of Dental Research of Dental Research they came to the conclusion that water temperature didn't make a difference.  Here's where we insert fancy medical speak:

The use of warm water during toothbrushing promoted root dentine wear similar to that produced by the use of cold water. The results suggest that warm or cold water may be used during toothbrushing without any additional damage to the patients' dental hard tissues.

I'm beginning to think it's a po-tay-toe, po-tah-toe thing.
