Types of Retainers for Teeth

After months or even years of orthodontic work, a retainer is what helps preserve your progress. Whether you’ve worn braces, clear aligners, or had minor tooth movement corrected, retainers play a vital role in keeping your teeth from shifting back. But not all retainers are created equal.

Here’s a guide to the different types of dental retainers, their pros and cons, and what to consider when choosing the right one for your needs.

Why Retainers Are Necessary

Once your teeth have been repositioned, it takes time for the surrounding bone and tissue to stabilize. Without a retainer, your teeth may gradually shift back—undoing your investment in orthodontic treatment.

Retainers are also sometimes used:

• To correct minor tooth movement

• To help with bite alignment

• To support speech improvement

Your oral healthcare provider will recommend a retainer type based on your specific needs, lifestyle, and dental history.

1. Removable Retainers

These retainers can be taken out and reinserted by you, making them a popular choice—especially for upper teeth.

There are two main types:

Hawley Retainers

• Made from a custom-fit acrylic or plastic base with a thin metal wire across the front

• Durable and adjustable by your orthodontist

• Available in fun colors and patterns

Pros

• Adjustable and repairable

• Long-lasting (up to 10 years)

• Allows natural bite contact

Cons

• Metal wire is visible

• May affect speech initially

• Easy to misplace if not worn regularly

Clear Plastic Retainers

Also known as vacuum-formed retainers or Essix retainers, these are made from clear, molded plastic and fit snugly over your teeth.

Pros

• Virtually invisible when worn

• Comfortable and easy to use

• Easy to maintain oral hygiene

Cons

• Not adjustable

• May yellow, crack, or wear out in 1–3 years

• Can become distorted if exposed to heat

Average Cost:

• Hawley: $150–$300 per arch

• Clear plastic: $100–$300 per tray

2. Permanent Retainers

Also called bonded or fixed retainers, these are custom wires that are glued to the back of your teeth usually the lower front ones and remain in place until professionally removed.

Pros

• Always working (no need to remember to wear them)

• Not visible to others

• Won’t affect speech

Cons

• Harder to clean around (floss threaders or water flossers recommended)

• Can break without you realizing it

• Must be removed or repaired by a dental professional

Durability: Up to 20 years with proper care
Average Cost: $250–$550 per wire (upper or lower)

Choosing the Right Retainer for You

There’s no one-size-fits-all option. In fact, many orthodontists recommend a hybrid approach a permanent retainer for the lower teeth (which tend to shift more) and a removable one for the upper teeth (where cosmetics matter more).

When making your decision, consider:

• How likely are you to wear a removable retainer consistently?

• Do you mind a retainer that’s visible?

• Are you willing to clean around a fixed wire daily?

• What’s your budget and does insurance help cover the cost?

Keep in mind that even after your orthodontic treatment is long over, your teeth can continue to shift over time as your jaw and facial structures age. For most people, wearing a retainer long-term even nightly is a small commitment for a lifetime of results.
