I gave it to my son to use.

He's a grown son, but it seems like he doesn't brush his teeth properly.

Use dental floss. Use an interdental brush.

He nags.

I tend to be a bit sensitive about dental care.

They tell me to make sure to brush my teeth even when I'm out.

It came as a gift.

I yield to my son.

I used a Philips one before

I use a regular toothbrush these days.

Kids who don't brush their teeth well

I think an electric toothbrush will clean better.
