However, before you start with any treatment, consider the following precautions. After all, whitening treatments have associated risks.
Whitening Under Supervision to Lower Associated Risks
Tooth discolouration is brought about by colour molecules. Whitening agents have the capacity to break down these molecules and lighten the shade of teeth from the inside out. The bleaching agents used in dental clinics and available from pharmacies all over New Zealand are quite safe to use since they have no effect on bonding materials and fillings.
Studies have revealed that bleaching agents such as carbamide peroxide and hydrogen peroxide are indeed safe when used in the right concentrations. This is ensured if you undergo tooth whitening under supervision from a licenced dentist. Peroxide can inflame the gums if used in high concentrations.
Tooth Sensitivity and Other Side Effects of Bleaching
If you ask about the possible side effects of teeth whitening, Tauranga-based dentists will definitely mention sensitivity. During the course of bleaching your teeth, you may experience increased sensitivity of the pulp chamber, which leads to discomfort while chewing food. Some people had to put up with this for three months, although it usually lasts for a few days. Other possible side effects are uneven whiteness and gum irritation.
Shade Rebound
In some cases, people who undergo power bleaching experience “shade rebound” after a week or two. This may be due to the increased vulnerability of teeth to staining. Power bleaching removes the pellicle of the teeth. Without this protective layer, your teeth may stain more readily. As such, post-power bleaching tooth care should be followed religiously.
Your teeth have huge potential to lighten a few shades. Learn about the different procedures and possible side effects before you undergo bleaching.
