I'm in my 30s and starting to notice some of my teeth are yellowing. Is this normal? What are safe ways to whiten? Is there anything that I can do the slow down the yellowing?

Natural teeth have a tendency to get darker as we get older. There are several more or less effective over-the-counter tooth whitening products and toothpastes available in drug stores and pharmacies that may be helpful in making your teeth lighter again. The most effective and safest way, however, is to do this under the supervision of a dental professional, who can assess the reason for the darkening and select the most appropriate solution.
The teeth may be discolored with “external” stains from tea, coffee, tobacco, red wine etc., which can only be removed with special cleaning and polishing instruments, preferably by a dentist or dental hygienist. If that’s the case, this cleaning should be done before any other tooth whitening procedure.
