When should you throw away a toothbrush?
Question:
Answers:
Hi! I've been in dentistry for over 25 years. I recommend that you change your toothbrush every 3-4 months and after a cold or serious infection. Boiling in water melts the plastic handle and weakens the brush. Do not do that. For 2 bucks toss it and get another. Do not use the brush so hard it fans out. You are not scrubbing the kitchen floor. Gum tissue is delicate and teeth can be worn done if you brush too hard. ONLY use a soft tooth brush that will get into the area around the tooth. Electric is fine as long as you get into the area behind your back teeth and the back of all your front teeth. I don't care what my patients use as long as they use it twice a day and floss. If you have any other questions, please ask. If sounds like you have a great attitude and will have your teeth your whole life. GOOD for you!! Keep up the good work. Marie
You can keep it as lon as you want. Always disinfect it, or throw boiling water over it ever 1-2 months.
dentists recommend every 3 months get a new one
usually they have a color stripe. when that begins to fade its time to get a new one. every two months should be ok for a toothbrush.
As soon as the bristles start to spread, once they do, they will scrape and injure your gums
