Patient discussion about brush

Q. do you know what are the pros and cons of the Sonic toothbrush from Oral B (electric tooth brush)? last night, my best friend raved about it for a whole hour. My dentist told me to use a soft brush (number 35) to clean my teeth and that the electric brushes are a bit over rated. My friend specifically told me about the Sonic product and told me that it also makes his teeth whiter. I wanted to know if anybody has any knowledge or experience from first hand about this product or any good information about it.

A. Thank you for the frank answer. I wonder if I can find a really soft electric toothbrush

A. Bad breath in most of the cases happens because of problems with mouth or teeth (like bacteria between your teeth or on the back of your tongue). You may consult a dentist to see if there is a problem that can be treated. You can also try to eat a good breakfast with fibers, drink water, chew gum for a several minutes, gargling with mouthwash or brush the back of your tongue and see if these things helps.

A. I agree with Dagmar you can loose some hair each day. But if you are loosing quite a bit you might want to see a specialist such as a dermatologist. Also make sure you don't have a thyroid condition. You can loose hair if you have an overactive or an underactive thyroid. I don't know how old you are but age is also a major factor as well.With the onset of perimenopause, Women tend to have thinning hair or they can loose some of their hair as well.
