DENTAL HEALTH ISSUES
How does fluoride work to protect my teeth from cavities?
Fluoride helps to fight cavities through a process called remineralization. A cavity usually starts as a very small weak spot in the enamel of a tooth. After continual bombardment by acid and bacteria, this weak spot can become a fully developed cavity. Acids play a major role in the cavity's process because they remove minerals (namely calcium and phosphorous) from the tooth, making it more susceptible to decay. This process is called demineralization. Fluoride counteracts this effect and actually helps to reverse demineralization by fostering the return of lost minerals to the demineralized site. This positive process of returning minerals to the mineral-starved site is defined as remineralization. Aquafresh® also fights cavities by helping to reduce the production of acids by physically removing the bacteria which are the source of acids that can actually cause teeth to demineralize. Additionally, Aquafresh® adds fluoride to the tooth's crystal lattice, making it more resistant to acid attack. In other words, Aquafresh® actually strengthens the tooth's outside protective enamel surface.
What are plaque, tartar and gingivitis?
Plaque is a gummy mass of microorganisms that grow on the crowns and spreads along the roots of teeth and is both colorless and transparent. Dental plaques are the forerunners of dental caries and periodontal disease. Tartar is hardened plaque deposited upon the teeth. Gingivitis is inflammation of the gums characterized by redness, swelling and tendency to bleed.
Is it safe to use fluoride toothpaste even if my water supply is fluoridated?
Major professional dental associations, including the Canadian Dental Association (CDA) and the British Dental Association (BDA), recommend that people of all ages use fluoride toothpaste twice daily, even if they live in an area with a fluoridated water supply. (Oral Care Issues Management Resource, July 2003) The recently issued Cochrane report reviewed 56 clinical studies covering more that 42,000 participants. The results show that the use of a fluoride-containing toothpaste provides a significant benefit (about 25% fewer cavities) even in areas where the water is fluoridated.

SOME FACTS ABOUT THE DIFFERENT KINDS OF AQUAFRESH
Can adults use Aquafresh® Kids Toothpaste?
Aquafresh® Kids Toothpaste is very similar to Aquafresh® Cavity Protection +Toothpaste. The main difference is that Aquafresh® Kids Pump has a children-preferred sugarless bubblegum flavor. All of the Aquafresh® Toothpaste products are equally effective at fighting cavities and are gentle enough for adults and children to use.
How does Aquafresh® Sensitive Toothpaste help sensitive teeth?
Teeth become sensitive when the nerve endings become exposed. Gum disease, excessive brushing, tooth grinding or general wear can expose nerve endings in the dentine. This makes the tooth sensitive to touch and to hot, cold and sweet things. Toothpastes for sensitive teeth, such as Aquafresh Sensitive, can help treat sensitive tooth pain in two ways: by soothing the irritated nerve and by sealing off the holes in dentine that lead to the nerve.
How do the Aquafresh® Whitening products whiten your teeth?
Aquafresh® Whitening toothpaste products contains ingredients that work as a gentle cleanser that whitens teeth by helping to break up and remove stains without bleach, peroxide, or harsh abrasives. Results should be visible after using one full-sized tube of one of the Aquafresh® Whitening products. Aquafresh® Extreme Clean PowerWhite has a high-cleaning silica, specially designed to polish away stains without excessive abrasion.
ABOUT AQUAFRESH® WHITE TRAYS®
How do you use / put on Aquafresh® White Trays®?
Carefully peel back foil from the lower tray and remove the tray from the container. Hold the tray so that the open ends of the "U" are pointing toward you. Place the tray on the lower teeth. Ensure that the edges of the teeth are into the gel at the bottom of the tray. Gently press the tray, moving the whitening gel downward around the teeth starting at the biting edge and working the gel to, but not above the gum line to ensure good contact with the teeth. Biting down on the tray may help to better secure the fit. Start with your front teeth and work outward to the end of the tray. The use of a mirror may be helpful until you become accustomed to tray application. Repeat the process for upper teeth (either at the same time or separately).
Keep the tray in your mouth for a minimum of 30 minutes and up to 45 minutes just one time per day. After each usage, remove tray from mouth and discard. You may want to rinse your mouth with water or brush with water and a toothbrush if you have gel residue on your teeth after the trays are removed. Repeat daily for a minimum of 5 days. For even better results, use for 7 days. To watch a demonstration video of how to apply the trays and how they work, please click here.
