What are braces for?

Traditional braces are permanently fixed onto your teeth for a period of time to help straighten them. Invisible Braces are similar where it’s worn 20-22 hours a day and removable during mealtimes.

What do retainers do?​

Retainers are designed to maintain the position of your teeth post teeth-straightening treatments such as braces or aligners. After braces make your teeth straight, their position might still shift. 

This is because the gums, bones and muscles of the mouth aren’t used to the new positions of your teeth. Habits like chewing cause teeth to shift, and therefore retainers are needed to maintain your teeth’s new position.

Do I need braces or retainers?

What would you like to achieve and have you ever had braces done before? If you’d like a straighter smile, braces are your best bet. Retainers are for when you’ve already straightened your teeth and want to maintain your beautifully straight smile!

Can I use my last aligner as a retainer?

Aligners are made with a unique material designed to move teeth. It has an average wear time of 1-2 weeks per set for optimal teeth movement. They’re not designed to maintain the position of your teeth for an extended period of time. This is because aligners are flexible and prone to breakage after its intended use.

Retainers are made from a more rigid material specially designed to maintain your teeth position. Your teeth are constantly moving throughout your lifetime and retainers will help to prevent your teeth from shifting too much.  

Can you wear retainers without wearing braces first?

For cases where teeth are only slightly crooked or crowded, it is possible to get retainers made to maintain your current teeth position. It is best to seek a consultation with your dentist if retainers are recommended for you as every individual is unique. Please note that wearing someone else’s retainer will not straighten your teeth as everyone’s mouth isn’t shaped the same.

Can retainers straighten teeth?

Retainers can’t straighten teeth like braces do. Braces apply constant and steady force to move your teeth into the correct position. If you don’t wear your retainers, your teeth may still shift. You may feel some discomfort while putting your retainer on especially if you’ve not worn your retainers for a few weeks. This is because your retainer is slowly pushing your teeth back into its proper alignment.
