WHAT ARE WHITENING STRIPS
Whitening strips are teeth products that can improve the color of the teeth by a shade or two. They are made of safe materials that cannot cause harm to the teeth or body. They are made of ingredients like:
- Polyethylene: This is an non toxic, flexible material that is the base of the strip.
- Hydrogen Peroxide or Carbamide Peroxide are the natural and safe bleaching agents in a strip. They are the main ingredients that are effective in whitening the teeth.
- PVP (Polyvinylpyrrolidone) & Carbomer are the adhesive agents that holds the strip to the teeth. They are very safe and harmless to the teeth but if overused, can irritate the gums.
- Water helps to keep the teeth hydrated while the strips work on them.
- PEG (Polymerization Ethylene Glycol) is the thickener, it makes the gel sticky and less watery.
- Glycerin is also a thickener that helps the strips to bind to the teeth. It has a sweet taste and safe as well.
- Sodium Hydroxide is a caustic soda that keep the pH of the mouth neutral, it helps to adjust the pH to avoid irritation.
- Acrylates Copolymer also helps to keep the strip in place while it works on the teeth.
- Sodium Saccharin is a sweetener that helps to improve the taste of the gel.
HOW DO WHITENING STRIPS WORK
It is a known fact that whitening strips can whiten the teeth. The carbamide peroxide or hydrogen peroxide in these strips bleach the teeth. They penetrate into the enamel (outer layer of the teeth) and dentin (deeper layer) to bleach the chromogens. These chromogens are found inside and outside the teeth, they cause stains.
The teeth can have two stains – extrinsic and intrinsic. The extrinsic stain is caused by environmental factors like smoking, drugs, foods and drinks and exposure to some metal. This stain affects the enamel. The intrinsic stains are caused by factors like tooth disorder, aging, genes, high fluoride and antibiotics. This stain occurs inside the teeth.
Whitening strips can work on both extrinsic and intrinsic stains, they are effective in whitening the teeth to some extent. However, if you want the maximum result, you can consider professional whitening treatment by dentists.
DO WHITENING STRIPS WORK ON YELLOW TEETH
Whitening strips can work on yellow teeth as well but the extent of the stain and how severe the stain is should be considered. The strips can whiten yellow teeth to a great extent but they do not really work on everyone. The strips can work but may take an extended period of time. It can take at least a week or two to see results. If the yellow stains on your teeth are much and severe, you can see a dentist to consider other viable options that are best for you.
DO WHITENING STRIPS WORK ON CROWNS OR VENEERS
Crowns and venners are made of porcelain or metal alloys, they are used to cover the teeth after root canal or breakage. Crowns and veneers are made to be resistant to stains but they can be stained sometimes. Whitening strips cannot bleach veneers and crowns as they cannot penetrate the stains on the crowns. The material in crowns do not respond to the strips or gel.
Whitening strips only works on natural teeth and not crowns or veneers no matter the brand. If you want to change the color of your crown or veneers, the dentist can replace the crowns or place another veneer on the crown.
DO WHITENING STRIPS WORK ON FILLINGS

DO WHITENING STRIPS WORK ON CROOKED TEETH
Whitening strips can work on crooked teeth but they are not the best. They work better in people with straight teeth because they are laid flat on the teeth surfaces. Crooked or misaligned teeth may not be flat enough for the strips to get to all sides and corners of the teeth.
This can make some areas of the teeth lighter than others and give the whole teeth an uneven look. You can whiten your teeth with the strips but the results will not be the same as people with straight teeth.
