Finishing braces or clear aligners is a big step, but treatment does not stop when they come off. Dental retainers help hold your teeth in their new positions while the bone and gums settle. If you are planning or finishing orthodontics, it helps to know what this stage involves.
At Good Choice Dental, we plan retention as part of orthodontic treatment and explain your options before your braces or aligners come off.
Quick Overview
- Dental retainers are custom-made appliances worn after braces or aligners to help keep teeth in place.
- Most patients receive a fixed retainer, a removable retainer, or both.
- The right type may depend on how your teeth were positioned before treatment.
- How long you need to wear one can vary from person to person.
Below, we explain the main types of retainers, how long they are usually worn and how to look after them.
Why Do You Need Dental Retainers?
Teeth can move throughout life. After treatment, the fibres and bone around each tooth need time to adapt. Without a retention phase, teeth tend to drift back towards their original position. A retainer helps support them.
What Are the Types of Retainers? 
- Fixed retainers, also called bonded or permanent retainers, are a thin metal wire glued behind the front teeth, often the lower teeth. You cannot remove them, but they need careful cleaning, as plaque buildup around the wire can lead to gum disease.
- Clear plastic retainers are thin removable trays that fit over your teeth. They are less noticeable but can wear or crack over time.
- Hawley retainers use a metal wire across the front teeth attached to an acrylic base. They are durable and can be adjusted.
Clear plastic retainers are the most common choice for the top teeth, and bonded retainers for the lower teeth. Your dentist will suggest the option that suits your teeth and lifestyle.
How Long Do You Need to Wear a Retainer?
Many patients wear removable retainers for most of the day at first, then move to nighttime wear. The same survey found around 85% of dentists recommended wearing retainers indefinitely. Follow the plan you are given, as it depends on your individual situation.
How to Care for Your Retainer
- Brush removable retainers gently with a soft toothbrush, cool water and mild soap.
- Avoid hot water, which can warp plastic.
- Store your retainer in its protective case when it is out of your mouth.
- Clean under a fixed wire with floss threaders or interdental brushes.
- Keep your follow-up appointments so the fit can be checked.
What If Your Retainer Breaks?
If a fixed wire comes loose or a removable retainer cracks, contact your dentist promptly. Teeth can shift quickly, and a replacement may be needed.

Frequently Asked Questions
Are dental retainers permanent?
A fixed retainer stays bonded in place, but it may need repair or replacement over time. Removable retainers can also wear out.
How many hours a day should I wear my retainer?
This depends on your treatment plan. Many patients start with most of the day, then move to nighttime wear.
Can I clean my retainer with toothpaste?
Toothpaste can scratch clear plastic retainers, so many dentists suggest avoiding it. Mild soap and cool water are a gentler option.
What happens if I stop wearing my retainer?
Your teeth may slowly shift. If you notice changes, speak with your dentist about your options.
Is a fixed or removable retainer better?
Each has benefits and drawbacks. The right choice depends on your teeth, your bite and how easily you can wear and clean it.
