A 46-year-old member asked:

is laser teeth whitening the most effective way to whiten your teeth?

Sometimes but....: First, they don't actually use lasers, just bright lights. In office whitening is more costly. I recommend custom take home trays that are generally more economical and can be reused in the future if necessary since you have the trays already and just use fresh whitening gels. Some people hate the hassle and don't mind the cost and for them perhaps it's the best option. Ask your own dds.

No: The absolute most effective whitening is achieved with trays worn for 1 - 2 hours a day for 7 - 14 consecutive days. These are fitted by a dental impression and the gel is dentist prescribed strength.

Yes and No: Teeth must be bleachable. Think of laser whitening as "jump-start". It will typically get teeth 4-8 shades lighter (depending upon what their starting color is). Teeth whitening is most effective when the dental bleach is on the teeth for long contact time. I'm old school, the best result&least sensitive is from 10% worn overnight for a number of consecutive nights (you stop when happy).
Dr. Don Millner

Lasers do not bleach: While many practitioners still incorporate lights or lasers as part off their tooth whitening process most will tell you they do such not for enhanced results but to satisfy patient's expectations. Most clinical studies state that the whitening effect is directly related to the strength (and freshness) of the peroxide combined with the length (20 min max) and amount of times it is applied.

Possible infection: It may or may not be related to the piercing since it is now one year down the line. If it is related then it could be an infection which you should have checked out.

Where can I purchase mouth guards for grinding teeth?

Dr. Shawn Murray
Dentistry 15 years experience
Mouth guards: Almost every dentist can make you a custom mouth guard. You shouldn't buy a mouth guard that is not made for you specifically or it can cause problems. Just like one size fits all shoes aren't a good idea.

Possibly: It is not a for sure thing that you would have an infection but those symptoms common for an infection that is draining such as an abcess. You may want to have a dentist take a look for you.

Fluid: Saliva doesn't necessarily have a role in cleaning your teeth. It would matter if you didn't have saliva while cleaning your teeth.
