What Is A Permanent Orthodontic Retainer?

You’ve just spent months (or even years) straightening your teeth – so what happens next? In order to stop your teeth from moving back out of alignment, you need to wear some type of retainer.

A permanent retainer is a great choice as it is effective, long lasting and discreet. In this blog, we’re going to tell you everything you need to know about this appliance, and why it is so important to wear one after your orthodontic treatment.

What is a permanent orthodontic retainer?

Also known as a fixed retainer, this appliance is a thin metal wire that attaches to the back of the teeth using dental adhesive. Permanent retainers hold your teeth in place 24/7, helping to prevent orthodontic relapse and future costly procedures.

This appliance is most often placed on the lower front six teeth. Whilst they can be placed on the upper jaw too, dentists usually avoid doing this as the wire is more susceptible to damage caused by biting and chewing. A common solution to this issue is wearing a removable retainer on the top teeth and a fixed one on the bottom.

Is a permanent retainer really necessary?

A retainer is the only way to have permanently straight teeth. Therefore, the experts at Yorkshire Dental Suite strongly recommend wearing a retainer once you have completed your orthodontic treatment. As mentioned earlier, it stops your teeth from moving while the surrounding bone and gum adjusts to their new position.

How long do permanent retainers last?

Typically, a permanent retainer lasts 5 – 10 years. However, if well cared for, it can provide up to 20 years of wear or even longer. To enjoy the full lifespan of this appliance, try the following aftercare guidance:

• Great oral hygiene is key: Brush twice a day for two minutes at a time with a soft-bristled toothbrush and fluoride toothpaste. Doing this helps to stop plaque from building up. Remember to be gentle and avoid placing too much pressure onto the wire.
• Floss daily: This is essential in order to prevent cavities and gum disease. Be mindful that a special type of floss and technique is required to avoid breaking the wire – your dentist will show you how to clean the area after fitting the appliance.
• Consider your diet: Hard, crunchy and sticky foods pose a risk of damaging your retainer. Avoid as much as possible or cut these foods into small pieces before consuming. Try chewing with the back of your teeth too.
• Visit the dentist: Two routine check-ups per year help to make sure your wire isn’t damaged, while two annual hygienist appointments keep the areas around the retainer clean. Do not hesitate to contact your dentist if you have any concerns about your retainer either – they are here to help.

How much does a permanent retainer cost?

The cost of a permanent retainer varies from clinic to clinic. If you go to a private practice, the average price is £150 - £400 per jaw. Many private clinics offer finance to help you spread the cost of the appliance over time, or you are able to pay in one instalment.

You can claim a permanent retainer on the NHS. However, it must be deemed a clinical necessity, for example, your dentist believes your teeth will move once your braces have been taken off. Patients under 18 usually receive it for free under their treatment plan, while adults may have it included in their braces price (£332.10).

Permanent retainer pros and cons

Are you currently undergoing orthodontic treatment and considering a permanent retainer? There are advantages and disadvantages to be aware of prior to having the appliance fitted.

Pros:

• Highly effective at preventing teeth from moving out of alignment
• Typically attached to the back of the teeth, making it very discreet
• Can last 20+ years if well cared for
• Do not require a person to remember to wear them
• As it is attached to the teeth, it cannot be lost

Cons:

• Susceptible to snapping and bending
• The wire can make flossing and teeth cleaning tricky
• Food may become trapped around the wire, leading to a build-up of plaque
• If the wire breaks, you will need to cover the cost of replacement
• Potential tongue irritation if it catches on the retainer

Can a dentist remove a permanent retainer?

Yes. The process is quick, painless and takes less than 30 minutes to complete. Your dentist may also clean the teeth if plaque has become trapped beneath the wire. Something to note is that there is a high chance your teeth will move once it has been taken off, unless you switch to a removable retainer.

Permanent retainer vs removable retainer

A removable retainer has the exact same purpose as its permanent counterpart – to protect the results of your newly straightening smile. Resembling a clear aligner (or sports mouthguard), this retainer is designed to be worn either overnight or 24/7, depending on your dentist’s directions.

There are key differences between the appliances. We have compared the two in the following data to help you make an informed decision about which to wear once your treatment has been completed.

Conclusion:

Now we have covered what to know about permanent retainers, you can consult with your dentist about whether a fixed or removable retainer is the best choice for your smile. Both are highly effective in preventing orthodontic relapse and maintaining your confident new smile for as long as possible.
