Whitening toothpaste is maybe a little misnamed category depending on your expectations. Extrinsic staining are stains that occurs on the outer surface of teeth, often near the gum margins. You will find a range of whitening toothpastes here that will help remove these surface stains but also contain the fluoride required to strengthen teeth. The first step in getting whiter, brighter teeth is thorough tooth brushing. Plaque biofilm forms on the teeth and picks up food and drink colours. Tea, coffee and red wine are common stains that gather on tooth surfaces. Plaque biofilm (sticky gel like substance) that has been left to mature on teeth will become yellow. This can be removed with thorough tooth brushing – especially around the gum line. Find out more about tooth brushing here.
These toothpastes will remove surface staining but may not bleach your teeth to the colour/shade you hope for. If a toothpaste does not actually contain hydrogen peroxide, or it contains carbamide peroxide at a level below 0.1% hydrogen peroxide it cannot internally help to whiten the tooth. Ingredients which reduce the staining on the tooth are typically fruit enzymes such as citrain and papain.
If using a whitening toothpaste for a couple of weeks doesn’t give you the brightness you want, tooth whitening by a dental professional will be required. Legally in the UK, only dental professionals can provide tooth whitening/bleaching using products that will bleach teeth. There are very good health and safety reasons for this. Not everyone’s mouth is suitable for bleaching so it is important that you see a dentist for assessment and provision of tooth bleaching/whitening treatment. Illegal tooth whitening by non dental professionals can result in permanent damage to teeth and gums. Fine out more http://www.bsdht.org.uk/news-1/how-dangerous-is-tooth-whitening-1
Some whitening toothpastes are very abrasive e.g. charcoal powder. The RDA helps give you an idea of how abrasive a toothpaste is. The higher the number the more abrasive the paste. Using an abrasive toothpaste and a hard toothbrush can cause tooth wear. Look at the RDA of toothpastes in our toothpaste guide. Compare with these with the RDA of those you will find on Growing Smiles. Curaprox BeYou Whitening – RDA of 50, Black is White which uses activated carbon, RDA is 59.
