Professional Teeth Whitening

Great question. Professional whitening uses stronger bleach. It works better and lasts longer than store-bought products like whitening strips or toothpaste. Your dentist also keeps watch over the treatment. This lowers the risk of sore gums or sensitive teeth.

When it is done the right way, teeth whitening does not harm tooth enamel. Enamel is the hard outer layer of your tooth. Still, it is important to follow the directions. A dental professional is happy to guide you. This helps you avoid any harm.

Often, yes. Sensitive teeth do not always mean you cannot whiten your teeth. It helps to tell your dentist that your teeth are sensitive. Then your dentist can pick the right way to whiten. This also helps keep any discomfort small.

Generally, yes. Professional teeth whitening is usually safe when a dentist does it. Your dentist uses bleaching gel at a safe, controlled strength. Your dentist also takes steps to protect your gums and the soft parts of your mouth from harm during the visit.

It can, a little, for some people. Teeth whitening may make your teeth sore for a short time. This is more likely if your teeth are already sensitive. Your dentist can suggest products to calm it, and fluoride products can help too. They keep discomfort low. It usually fades in a few days after the treatment.

Results are different for each person. They depend on your natural tooth colour, the kind of stains you have, and the whitening system used. Most people end up with teeth that are several shades lighter. Your dentist will tell you what to expect for your own teeth, and you are welcome to ask.

Professional whitening works well on stains on the outside of your tooth. These are called extrinsic stains. Foods, drinks like coffee, tea and red wine, and smoking can cause them. It may work less well on stains inside the tooth. These are called intrinsic stains. Some medications or an injury to a tooth can cause them.

Not everyone, and that is okay. Teeth whitening is not right for everyone. It is not advised if you have gum disease, cavities, exposed tooth roots or sensitive teeth. It also does not work on crowns, veneers or fillings, because they do not react to bleaching gel.

Generally, no. Whitening gel does not change crowns, veneers or fillings. If you have any of these, they may need to be replaced or changed so they match the colour of your whitened teeth. That way your smile looks even.
