Hydrogen Peroxide Teeth Whitening, Teeth Whitening Nyc, Teeth Whitening Bristol 

The obvious solution is to visit your local dentist?

But the chances are, you’ll have to fork out anything from $1,000 - $3,000.
And most people simply can’t
But what you REALLY need to know is that dentists use a range of toxic chemicals such as Hydrogen Peroxide and Carbamide Peroxide - which are both used as BLEACHING AND DISINFECTANT AGENTS and can cause horrific side effects.
In fact, here’s just a small selection of the most common side effects I saw
SIDE EFFECT #1: PROLONGED TOOTH SENSITIVITY
SIDE EFFECT #2: SHRINKING/RECEDING GUMS
SIDE EFFECT #3: BLEEDING & MOUTH BLISTERING/BURNT GUMS
SIDE EFFECT #4: STOMACH PAIN, DIARRHOEA & VOMITING
SIDE EFFECT #5: PAINFUL THROBBING
SIDE EFFECT #6: THERE ARE NO GUARANTEES IT WILL EVEN WORK!
Ok, it's not really a side effect, but it's a definite problem! The fact is, despite what you've probably been told, teeth whitening techniques won't work for everyone.

This is because (as I mentioned earlier) tooth staining is also caused by antibiotics such as tetracycline, which discolours the tooth enamel itself.

Tired of those yellow teeth, no longer makes the decision from now
