Will bleaching or tooth whitening damage my enamel?
NO! Tooth whitening changes the colour of the stains within your enamel but keeps your enamel intact.
Are there any long term effects to whitening my teeth?
Tooth whitening has been around since the 1950's. To date, there have been no adverse long term affects to tooth whitening.
Does tooth whitening cause any dental pain?
Tooth whitening can cause temporary sensitivity to the teeth. This sensitivity varies between patients. If you usually have sensitive teeth to sweets and cold then the chances of sensitivity while tooth whitening is highly likely. This sensitivity is only residual and may last a few hours or up to a day or two. Some patients also experience gum irritation caused by the whitening gel. This appears as a white area on the gums and is caused by the gel having prolonged contact with the gum tissue. The gum colour will return within a few hours, but can be sensitive for a few days.
Why do some dentist think that root filled teeth need dental crowns to strengthen them?
The problem with root filled teeth is not that they are weak; it is that without the nerve fibres within the pulp of the tooth we lose some degree of sensory perception (proprioception). Vital teeth can detect instantly the presence of extra force if we bite on something too hard. We immediately flinch and let go. Root filled teeth lack this reflex.
Does root canal therapy weaken a tooth?
In short NO!.
According to the journal of Endodontology (Huang etal 1991, J Endo 1991; 18; 209-215) whilst root canal may cause some dehydration to the tooth, this does not affect the physical or mechanical properties of the tooth.
