The Hidden Damage Nail Biting Causes to Your Teeth

Nail biting isn’t just a bad habit—it can harm your oral health too. Every time you chew your nails, you put unnecessary stress on your teeth and gums. This can lead to:

Chipped or cracked teeth from constant pressure

Worn enamel that makes teeth more sensitive

Shifting teeth or jaw strain over time

Gum injuries and infections from bacteria hiding under nails

Finally have nails again!
I’ve been biting my nails for 30 years and nothing worked until this polish pen. In just 2 months my nails are healthy and strong, and the bitter taste instantly stops the urge to bite. Truly effective!
Flora
It really helps!
I’ve tried a few different nail bite deterrents like this, but this one works best. The taste is nasty, so it really did the trick. It doesn’t take much, it’s super thin and dries fast. This is about 1 month into using. My nails before were super short, below where the white part of the nail starts. Would definitely recommend.
Amy
Works Great!
I definitely recommend this product. First photo is from May 10th. Last photo is June 8th. I stopped biting and I finally have pretty nails. Just need to be patient and reapply the pen maybe once every 2-3 days.
Alex
