A RealAge answered. You can expect to pay anywhere from $10 to $40 for a tray-based teeth whitening kit purchased over the counter (OTC) from a pharmacy or other retail store. You can also purchase tray-based teeth whitening systems from dentists. These systems feature custom-fit tooth trays or mouthpieces, which is why they are significantly more expensive than OTC tray-based teeth whitening kits. Purchasing a tray-based teeth whitening system from your dentist may cost up to $500.
Planking (or the Lying Down Game) is an activity consisting of lying face downâsometimes in an unusual or incongruous location. Both hands must touch the sides of the body. Some players compete to find the most unusual and original location in which to play.lanking can include lying flat on a flat surface, or holding the body flat while it is supported in only some regions, with other parts of the body suspended.
Then your body will start shaking and every muscle will be screaming in agony, begging you to surrender. And when you do give in, itâs the most wonderful feeling on earth. The plank has been a staple in gym workouts, exercise classes such as Pilates and yoga, and with personal trainers for years. Itâs brilliant for strengthening your bodyâs core â the muscles in your torso that keep you stable and balanced.
