If you want a delightful smile, consider these reasonably priced teeth whitening strips as they can deliver the results of dental surgery. But do they really work? What are the pros and cons? Let’s take a look at how the treatment works.
You should always check with your dentist before undertaking any form of teeth whitening. Note that teeth whitening strips are not effective on fillings, veneers, caps, crowns or brown teeth.
How whitening strips work?
Drinks such as red wine, cola, coffee and tea can stain your teeth. Tobacco products, some medications and genetic factors can also contribute to discolouration.
Stains build up gradually in the tooth enamel’s outer layer. Whitening strips contain a fine layer of the active ingredients hydrogen peroxide or carbamide peroxide, stuck to a bendy plastic strip that fits across the teeth. The bleaching agent penetrates surface stains, tooth enamel and dentin (the bony tissue beneath the enamel) to remove stains from deep within the teeth.
White teeth strips are generally used once or twice each day for up to two weeks. Most home teeth whitening kits leave teeth one or two shades whiter according to a 16-shade bleaching chart. The final results vary depending on the individual and the level of discolouration.
Advantages of using teeth whitening strip
The adaptable nature of the plastic conveniently adapts the form and positioning of your teeth.
Because just one side of the strip is covered with the Whitening agent, it works as both a barrier to help to prevent the whitener’s dilution and minimise its contact with soft tissues of teeth.
This helps to enhance performance and lower the user’s possibility of negative effects.
Because the manufacturer applies the whitener, the dosage you make use of is extremely controlled and regular. This assists to guarantee foreseeable bleaching outcomes as well as reducing the threat for negative effects.
As compared to all various other fairly reliable home methods, this is possibly the simplest, least-messy means to bleach your teeth.
Heavy stains may not disappear
As teeth whitening strips don’t have as much bleach in as dental surgery teeth whitening treatments, they’re best for people with only light staining or discolouration.
While home teeth whitening kits can tackle stains on the enamel, other kinds of discolouration are more problematic. For example, with advancing age, brown or blue dentin may become visible. Dentin may also be dark if a tooth has previously been injured.
Be warned that excessive whitening may cause weak enamel, which can make your teeth look translucent, grey or blue.
Other types of sensitivity include:
changes to tooth enamel, such as greater softness or roughness
erosion of restorations, such as fillings.
Dental hygiene and safety
Whitening strips are generally safe, provided that you follow the directions. Using them too often or leaving them on too long may lead to side effects.
If your teeth are sensitive, use a toothpaste for sensitive teeth starting a week before the whitening, and carry on using it during your treatment. Consider skipping a day of treatment to combat sensitivity, and avoid very hot and cold drinks.
Try sipping colas, teas and coffees through a straw to minimise discolouration during treatment, and swill your mouth out with water after eating if you have had a meal containing strongly coloured foodstuffs.
