Questions and answers

What is in the Boost Teeth Whitening Kit?

The kit pairs a carbamide peroxide gel with a lightweight LED mouthpiece and a shade guide. You apply the gel, wear the light for a set session, and repeat over several days. It suits people with mild staining from coffee, tea or smoking, not deep intrinsic discoloration.

Does the Boost whitening kit cause sensitivity?

Peroxide gels can cause temporary tooth sensitivity and gum irritation, especially at higher concentrations. Boost's kit is milder than in-office treatment, but users with sensitive teeth or gum disease should check with a dentist first. Stop if pain persists.

What does the Boost ebike conversion kit include?

It typically includes a hub motor wheel, a battery pack, a controller, a throttle or pedal-assist sensor, and mounting hardware. You fit it to an existing bike rather than buying a new ebike. Check your bike's dropout width and brake type before ordering, since fit varies.

Is the Boost conversion kit legal where I ride?

Rules differ by country and state. Many places cap assisted speed and motor wattage for road use, and some require the motor to cut out above a set speed. Confirm your local limits before riding on public roads or trails.

What warranty and returns apply to Boost products?

Terms vary by product and seller, and the whitening kit and conversion kit are usually handled differently. Batteries and motors often carry a shorter coverage period than the rest of the kit. Check the specific store's policy before buying.

Are there Boost discount codes?

Deal.ai checks what Boost products actually cost at every store, so a real markdown shows on this page as a deal as soon as it starts, and each product's page has its price history to tell a sale from its usual price.
