Is it safe for me to have electrotherapy beauty treatment if i have fixed orthodontics?

Yep: The currents or electric strength from beauty treatments is not strong enough to "travel" thru your skin and to your teeth. Just try not to have a bracket zapped directly. But that probably won't bother things either unless it is done repeatedly.

Yes: Certain imaging tools are not warranted with braces, i.e. Mri's, as the metal throws shadows and obscures anatomic structures and makes diagnoses more difficult. I see no reason why electrolysis for facial hair or similar procedures would be contraindicated by braces. I have never seen or heard of electrical conductivity through normal orthodontic appliances.

Yes: Excellent recommendations by the other doctors here. If you are still concerned, please ask the person providing the electrotherapy to contact your orthodontist.

Yes: There is no contraindication to electrotherapy beauty treatment.

Same as...: Safety is the same as if you were having electrotherapy beauty treatments and were not wearing braces.

You will be fine: The safety concerns are the same whether or not you have braces. You will be fine.

No worries: there is no way that the level of electricity would be strong enough to worry about. Have fun!
