Teeth are made up of 3 layers levels:

  1. enamel : that is the tough outer layer of your tooth
  2. dentine : that is soft
  3. pulp : that is the inner layer with vessels and soft tissue

The natural colour of teeth falls in between white to yellow and will have shdaes of red and grey colours. Typically, grey color shades in teeth may increase as you get older. Teeth enamel also thins through wear and tear, the darker dentine layer can begin to show through and abosrb minerals from the pulp making teeth appear yellowish in color.

Take-home kit allows you to perform whitening at your own time in the comfort of your home. Personalized bleaching tray enables less gum irritation compared to over-the-counter kits because the tray fits perfectly over specific teeth. There are no over-spills and you have the security that the whitening agent is a certified whitening gel.

2. DIY teeth-whitening kits or home bleaching kits

#1 – benefit 1

Home bleaching kits enable you to control the place and time to have whitening done.

#2 – benefit 2

For individuals with a tendency for sensitive teeth or who cannot open their jaw for long periods of time required for in-office whitening, take-home bleaching kits may be suited to them to whiten a lusterless teeth. Home bleaching kits normally contains a lower concentration of whitening agent and using the product less often may help reduce sensitivity. The whole whitening process will however take longer.

Before you purchase a home bleaching product, do first check with your dentist on the type of teeth stains you have to avoid the waste of your finances, effort, time or perform a treatment that may not work or perhaps is detrimental to your teeth condition type.

Choose a reliable whitening brand that has certifications on product safety and has been quality controlled. You may like to do a background check on the credentials of your whitening product. There are counterfeit and non-effective or even potentially harmful products on the market. Consider safety first before undergoing any cosmetic dentistry.

Follow your home bleaching instructions of your trusted take-home whitening kit. Using more of a whitening product or placing on for extended period of times will not help increase the whitening process but can actually cause harm to your teeth.

DIY teeth whitening may also come in the form as a tooth-whitening pen or adhesive strips. Regardless of each application form, home bleaching and dentist whitening procedures normally uses active chemical called peroxides to bleach teeth.

3. Teeth whitening toothpaste

Whilst take-home kits and in-office teeth whitening gels contains carbamide peroxide or hydrogen peroxide that chemically bleaches both surface stains and the tooth itself, most tooth-whitening toothpaste uses some form of abrasive components to remove surface stains adding in some other ingredients.

Tooth whitening toothpaste targets to physically clean of rub stains off teeth surface. Its levels of abrasives are generally low and does not wear teeth surfaces down. Foaming agents clean teeth surface. Polyvinylpyrrolidone (PVP) or others ingredients (such as tetrasodium pyrophosphate, pentasodium triphosphate, citric acid, sodium tripolyphosphate) chemically alters the electrical charge to prevent stains from sticking to teeth.

In general, whitening toothpastes may be used for surface stains and teeth cleaning, with limitations on its whitening effect.


How does in-office whitening and home bleaching work?

The active ingredient that whitens teeth is peroxides in the form of carbamide peroxide or hydrogen peroxide. Carbamide peroxide releases hydrogen peroxide in the presence of water. Hydrogen peroxide chemically bleaches teeth on the outer surface and within the inner tooth itself. Peroxides can lighter teeth beyond your natural colour at a high enough concentration.

DIY home teeth-whitening products normally should not exceed a certain peroxide percentage. Different countries have different rules regarding the permitted concentrations of hydrogen peroxide released by products and who may provide these. This is to limits the risks of toxicity and is not based on whitening effects to your teeth. Some countries do not permit more than 0.1% hydrogen peroxide whereas other countries may allows products of up to 12% hydrogen peroxide to be sold over the counter.

At your dentist office, the peroxide levels used for in-office teeth whitening are usually higher of up to between 20% and up to 35% hydrogen peroxide to enable faster whitening effect. Home bleaching gels from your dentist office may also be slightly stronger then over-the-counter bleaching kits and is administered based on their professional judgment one the suitability of concentration level for each individual.

Weaker concentrations of peroxide normally act at the surface of the tooth enamel compared to higher doses done at your dentist’s office.
