Most people with discoloured teeth will know that while the effect can be noticeable, it doesn't exactly boldly stand out. Teeth may have a yellow hue, or may even appear brown in extreme cases—but this is hardly going to surprise you. What may be an (unpleasant) surprise is when your own dental discolouration seems to be green. What on earth could be making your teeth turn green? And is it just a simple case of whitening that green away?
Green stains on your teeth are likely to be subtle. It won't look as though you have flecks of spinach stuck between your teeth, although green discolouration may look more striking than yellow or brown stains—simply because it's an exception to the more common shades of staining. Its irregular nature means that a specific type of teeth whitening must be utilised.
Inadequate Oral Hygiene
The bad news is that, when it comes to permanent teeth, those green patches can be literal patches of bacteria and fungi (typically penicillium and forms of aspergillus). As such, the issue can be caused by inadequate oral hygiene. There may also be irregularities with the formation of your dental enamel, creating microscopic catchments where fungi can accumulate. Before you rush out to buy a teeth whitening kit, there are a few things you need to know.
Simply bleaching your teeth using an over-the-counter product may not provide the desired results. There will be some changes, but the overall whitening effect will be negligible. You'll need assistance from your dentist—not only in removing this green discolouration but also in ensuring that it doesn't bother you again.
Removing Green Stains
This fungal growth is likely to have affected your dental enamel. Beneath the growth, your enamel may have demineralised. Your dentist can't simply scrape the growth away, as this will further damage your enamel. It can instead be lightly polished, with the remaining discolouration removed using hydrogen peroxide. Your teeth can now be whitened, but given the potential demineralisation of certain parts of your teeth's surface areas, it's best to have your dentist perform this service. This allows your teeth to be safely whitened, achieving a uniformity of colour (which is kind of the point of a whitening treatment). Your dentist will also go through your oral hygiene practises, identifying areas in which you need to improve.
Green patches on your teeth must be treated by your dentist. Their removal will make a big difference, and once this has been safely accomplished, your teeth can be whitened.
