If you're in need of orthodontics and are undecided as to which of type of braces you should go for (i.e. clear Invisalign braces or ones made from stainless steel), here are some examples of situations in which Invisalign might be a more appropriate choice.
You are worried about post-treatment discolouration
Orthodontic patients can sometimes experience post-treatment discolouration, as a result of plaque getting stuck in the areas where their teeth and braces meet, leading to the gradual destruction of their enamel, which then leaves the dentin substrate (a layer of the tooth that is yellowish in colour) exposed. When this discolouration occurs, the patient will usually have to go to their dentist to have either veneers or crowns added to their teeth to cover it up.
If this is something you are worried about, then clear braces might be more suitable for you than stainless steel ones. The reason for this is that if you opt for the latter, the opaque braces might obstruct your view of your own teeth and make it harder for you to see and remove the build-up of plaque on them. This could then increase the chances of this plaque causing irreversible damage to the enamel.
Conversely, if your braces are transparent, you will be able to see almost the entire surface of each tooth and will, therefore, be able to spot any accumulation of plaque. You can then either brush it away or have it scraped off by your dentist before it leaves permanent marks on your teeth.
You have a nickel allergy
If you are allergic to nickel, then you might need to get Invisalign braces, which are made from a type of resin. The reason for this is that metal braces are usually made from stainless steel, an alloy that contains nickel. If you get metal braces and you have an extreme nickel intolerance, you could potentially experience contact dermatitis in the areas of your mouth where the braces come into contact with your gum and cheek tissue.
Whilst not everyone who has this particular allergy will experience a reaction when they wear stainless steel braces (as some stainless steel orthodontics contain a very low percentage of nickel), it is important to understand that it could happen to you.
If this does occur, not only would you have to get the braces removed and get refitted with clear ones but you may also have to get the injuries caused by the contact dermatitis treated by your dentist. This could make your orthodontic treatment far more complicated than it needs to be.
