When orthodontic treatment is completed, the most important phase begins—maintaining your results. Retainers are essential for holding your teeth in their corrected positions after braces or aligners. Without proper retainers, teeth gradually shift back, reversing the investment of time, effort, and money. At Excella Orthodontics in Kolkata, Dr. Sayali Pradhan and Dr. Prasoon Killa emphasize that retainers are not optional; they are a mandatory part of every orthodontic treatment plan.
This detailed guide explains everything about retainers after braces: types, cost, durability, care, and choosing the right option based on your teeth and stability needs. Whether you used metal braces, ceramic braces, or clear aligners, understanding retainers ensures your smile remains aligned for life.
A retainer is a customized orthodontic appliance designed to hold your teeth in their final positions after treatment. Once braces or clear aligners straighten the teeth, the periodontal ligaments need time to stabilize. During this period, teeth naturally tend to drift back due to memory of previous positions.
Retainers prevent:
• relapse or shifting
• crowding in lower front teeth
• spacing returning
• bite issues reappearing
• rotation of teeth
• long-term orthodontic relapse
Patients often assume that once braces or aligners are removed, the results are permanent. However, orthodontists stress that retainers for teeth are a lifelong commitment. Whether you choose a removable dental retainer or a fixed ortho retainer, the key is consistent use.
Teeth are held in the bone by elastic ligaments. During braces treatment or aligners treatment, these ligaments stretch and remodel. Even after alignment is complete, the ligaments remain flexible for months. This is why dental retainers after braces are crucial for stabilization.
Factors that increase relapse risk:
• previous severe crowding
• spacing cases
• rotated teeth
• extraction cases
• periodontal conditions
• inconsistent retainer wear
At Excella Orthodontics, Dr. Prasoon Killa explains that for many patients, a combination of a bonded lingual retainer and a removable Essix retainer gives the best long-term stability.
A classic orthodontic retainer with an acrylic base and stainless steel wire.
Features
• long-lasting
• adjustable
• durable
• allows minor corrections
Best For:
Patients who need durability and minor post-treatment adjustments.
Limitations:
Visible wire, slightly bulky.
A transparent plastic retainer that fits snugly over the teeth. These clear retainers are the most popular today.
Features
• aesthetic and nearly invisible
• lightweight
• good for maintaining alignment
• fits similarly to clear aligners
Best For:
Patients seeking transparent retainers for post-braces retention.
Limitations:
Susceptible to wear and cracking over time.
A thin wire permanently bonded to the back of teeth—typically the lower front six.
Features
• maintains alignment 24/7
• invisible from the front
• recommended for crowding cases
• strong protection against relapse
Best For:
Patients with a history of severe crowding or those who forget to wear removable retainers.
Limitations:
Requires careful cleaning; plaque may accumulate if hygiene is poor.
Similar to Essix retainers but made with a slightly different manufacturing technique.
Features:
• aesthetic
• comfortable
• effective for upper and lower retention
A sturdier version of a fixed ortho retainer, often recommended for highly unstable cases.
Best For:
Long-term stability without depending on compliance.
• Transparent Retainer – generic term for plastic clear retainers
• Mouth Retainer – used for protection and retention
• Orthodontic Retainer for Teeth – any retainer prescribed after braces
• Night Retainers – retainers worn only at night after stabilization
Different retainer types serve different needs.
Here’s a summary:
| Retainer Type | Best For | Visibility | Durability | Compliance Needed |
|---|---|---|---|---|
| Essix Retainer | General retention | Invisible | Moderate | Yes |
| Hawley Retainer | Adjustable needs | Visible | High | Yes |
| Fixed Retainer | Severe crowding | Invisible | High | No |
| Clear Plastic Retainer | Cosmetic retention | Invisible | Moderate | Yes |
| Bonded Retainer | Long-term stability | Invisible | High | No |
Most patients at Excella Orthodontics receive:
• Fixed lingual retainer (lower teeth)
+
• Essix transparent retainer (upper teeth)
This combination offers the highest stability.

₹3,000 – ₹12,000
₹3,000 – ₹15,000 depending on treatment plan
At Excella Orthodontics in Kolkata, retainers are custom-made using high-quality materials. Patients receive guidance on which retainer type offers the best long-term results.
Retention duration depends on tooth stability.
• Removable retainers worn full-time
• Fixed retainers monitored regularly
• Removable retainers nightly
• Fixed retainers remain bonded
• Night-only wear recommended indefinitely
Teeth continue shifting with age, so long-term retainer use is strongly advised by orthodontists.
New retainers may feel snug. This is normal and indicates proper retention.
Slight lisp for the first few hours; speech normalizes quickly.
Temporary increase in saliva production, especially with Hawley retainers.
Common with new Essix retainers; resolves in a day or two.
To prolong retainer life:
• rinse retainers with cold water
• avoid hot water (warps plastic)
• clean using aligner cleaning foam or aligner cleaning tablets
• use soft toothbrush for gentle cleaning
• avoid toothpaste on clear retainers (causes scratches)
• store in a protective case
• keep away from pets
• avoid biting down on removable retainers
For fixed retainers:
• use floss threaders
• maintain regular scaling and polishing
• avoid biting hard foods on front teeth
Dr. Sayali Pradhan emphasizes that good hygiene prevents tartar buildup around bonded retainers.
Teeth are guided into position using brackets and wires. Ligaments require stabilization, making retainers crucial.
Retainers are still essential because aligner treatment also moves teeth using controlled pressure. Clear retainers mimic aligner fitting, making them ideal post-aligner retention solutions.
Replace immediately to prevent relapse.
Contact orthodontist urgently; alignment may shift within days.
Requires quick repair to avoid movement.
Indicates teeth are shifting; consistent wear needed.
| Feature | Aligners | Retainers |
