Can You Have Braces Twice? Understanding Orthodontic Relapse in Adults

If you had braces as a teenager and have noticed your teeth gradually shifting back, you are far from alone. Many adults find that teeth which were once straight have moved over the years, sometimes to the point where the original improvement is partly or fully lost. This is known as orthodontic relapse, and it is one of the most common reasons adults enquire about having braces for a second time.

The good news is that repeat orthodontic treatment is often possible. However, suitability depends on several individual factors, and the right approach may be different from what you had the first time around. At our London dental practice, we regularly see patients in this situation and understand how frustrating it can feel.

Why Do Teeth Move After Braces?

Teeth are not fixed rigidly in the jaw. They are held in place by a network of fibres within the gum and bone, and these tissues have a natural tendency to remodel over time. After braces are removed, this remodelling process can gradually cause teeth to drift back towards their original positions — particularly if retention is not maintained.

Several factors can contribute to post-orthodontic tooth movement:

• Irregular retainer wear — retainers are designed to hold teeth in their corrected positions while the surrounding tissues stabilise. If retainer wear is reduced or stopped too early, some movement is likely.
• Natural age-related changes — as we age, the lower front teeth in particular have a well-documented tendency to crowd, even in people who have never had braces. This is considered a normal part of dental ageing.
• Changes in habits — habits such as tongue posture, mouth breathing or clenching can place ongoing pressure on the teeth, contributing to gradual shifting.
• Gum and bone changes — periodontal disease, bone loss or changes in gum support can affect how stable the teeth are in their positions.

It is worth noting that some degree of movement can occur even in patients who have worn their retainers consistently. Teeth are living structures, and a small amount of settling over many years is not unusual. Each person's experience is different.

When Might a Second Course of Braces Be Considered?

Not everyone who notices a slight change in their teeth after previous orthodontics needs to repeat treatment. In many cases, minor settling is cosmetically acceptable and does not cause functional problems. However, there are situations where a second course of braces or aligners may be worth discussing with a dentist:

• Mild crowding or rotations at the front — the most common concern, where the lower or upper front teeth have become noticeably uneven again.
• Bite changes that affect comfort — if the way the teeth come together has shifted enough to cause discomfort, difficulty chewing or jaw tension.
• Cleaning becoming more difficult — overlapping or crowded teeth can trap food and plaque more easily, potentially increasing the risk of decay or gum disease.
• Cosmetic dissatisfaction — some patients simply feel self-conscious about the change and would like to restore the alignment they once had.

It is important to distinguish between cosmetic alignment concerns and more complex orthodontic needs. A short course of treatment may address mild relapse at the front of the mouth, while more significant bite issues may require a more comprehensive plan. A dentist can help clarify which category your situation falls into.

Treatment Options if You Have Had Braces Before

Adults returning for a second round of orthodontic treatment have broadly the same options as first-time patients, though the choice will depend on the type and extent of movement needed.

Fixed braces

Traditional fixed braces remain an effective option for a wide range of orthodontic movements. They may be recommended where more precise control is needed, or where the relapse involves the bite as well as the visible front teeth.

Clear aligners

For many adults with mild to moderate relapse, clear aligners in London can be a suitable option. These removable trays are less visible than traditional brackets and wires, and they allow normal brushing and flossing throughout treatment. However, aligners are not appropriate for every type of tooth movement, so the dentist will assess whether they are right for your particular case.

In some relapse cases, the treatment time may be shorter than the original course of braces, particularly if only a small number of teeth need to be repositioned. That said, treatment length varies considerably from person to person, and it is not possible to give a reliable estimate without a clinical assessment.

The Role of Retainers After Second-Time Treatment

If there is one lesson that orthodontic relapse reinforces, it is the importance of retention. After any course of braces or aligners — whether it is the first or the second — retainers are essential for maintaining the result.

There are two main types of retainer:

• Removable retainers — clear, custom-made trays (similar in appearance to aligners) that are typically worn at night. They hold the teeth in position while the surrounding tissues settle.
• Fixed (bonded) retainers — a thin wire bonded to the back of the front teeth, usually the lower arch. These are not visible from the front and provide continuous retention without the patient needing to remember to wear them.

Many dentists now recommend long-term or indefinite retainer wear, particularly for patients who have already experienced relapse. The specific advice will depend on your individual case, but the general principle is clear: if you want your teeth to stay straight, retainers need to remain part of your routine.

Your dentist will explain which type of retainer — or combination — is most suitable for you, and how often it should be worn. Following this guidance closely is the most effective way to protect the investment of time and effort that goes into orthodontic treatment.

Potential Benefits and Considerations of Having Braces Twice

Potential benefits

• Improved alignment — straightening teeth again can restore the appearance of the smile and help the patient feel more confident.
• Easier cleaning — well-aligned teeth are generally easier to brush and floss effectively, which may support long-term oral health.
• More balanced bite — correcting any bite discrepancies that have developed may improve comfort and reduce uneven wear on the teeth, though individual outcomes vary.

Things to consider

• Time commitment — orthodontic treatment requires regular appointments and, in the case of aligners, consistent daily wear.
• Cost — repeat treatment is an additional financial commitment, and it is worth understanding the fees involved before deciding.
• Long-term retention — a second course of treatment only works if it is followed by diligent retainer use. Patients should be prepared for this ongoing commitment.
• Individual variation — results depend on the complexity of the relapse, the health of the teeth and gums, and the patient's response to treatment. No two cases are the same.

How Much Might Repeat Orthodontic Treatment Cost in London?

The cost of a second course of braces or aligners depends on several factors, including:

• The type of appliance used (fixed braces or clear aligners).
• The complexity of the case and the number of teeth that need to be moved.
• The estimated treatment duration.
• Whether additional procedures — such as professional teeth cleaning or restorative work — are needed beforehand.

Taking the Next Step if You Are Considering Braces Again

If your teeth have moved since your first course of braces and you would like to explore your options, the most helpful starting point is an orthodontic consultation. During this appointment, the dentist will examine your current tooth positions, assess your bite, check your gum health and discuss your treatment history. Based on this, they can explain whether repeat treatment is appropriate and, if so, which approach may suit you.

There is no obligation to proceed, and a consultation is simply an opportunity to understand your situation and ask questions. Many patients find it reassuring to know what is possible, even if they decide to take time before committing.
