Why Retainers Are Essential After Invisalign or Braces

20th May 2026

Completing orthodontic treatment is an exciting milestone. After months of wearing braces or Invisalign aligners, many patients are delighted to see their newly straightened smile.

However, an important part of orthodontic treatment begins after the active treatment phase is complete. This stage is called retention, and it involves wearing retainers to help maintain the final position of the teeth.

If you are considering Invisalign treatment in Fareham, it is important to understand that retainers play a key role in protecting the results of orthodontic treatment.

Why teeth can move after orthodontic treatment

Teeth are supported by surrounding bone and ligaments. During orthodontic treatment these structures adapt as the teeth gradually move into their new positions.

After treatment finishes, the teeth can have a natural tendency to move slightly. Retainers help stabilise the teeth while the surrounding tissues adapt to the new alignment.

What types of retainers are used?

There are several different types of orthodontic retainers. The most common options include:

• Fixed retainers – a thin wire bonded behind the front teeth
• Removable clear retainers – transparent retainers that fit over the teeth
• Removable wire retainers – traditional retainers with a small wire across the front teeth

Your orthodontist will recommend the most suitable retainer based on your individual treatment.

How long do retainers need to be worn?

Retainers are usually worn full-time initially and then at night long term. Orthodontists often recommend continuing nighttime retainer wear indefinitely to help maintain the alignment achieved during treatment.

This helps reduce the risk of teeth gradually moving over time.

What happens if retainers are not worn?

If retainers are not worn as advised, teeth can slowly shift from their corrected positions. This is sometimes called orthodontic relapse.

Wearing retainers as recommended helps protect the investment patients make in their orthodontic treatment.
