Many adults had braces as teenagers, only to see their teeth slowly drift back out of line years later. This is called orthodontic relapse, and it is very common. The good news is that it is usually much easier to correct the second time, and clear aligners are often an ideal solution for busy adults.
Teeth sit in bone and are held by fibres that have a memory of their old positions. Without a retainer, these fibres and the natural forces from your tongue, lips and bite can gradually pull teeth back. Teeth also continue to move slightly throughout life due to ageing, which is why lower front teeth often become crowded in adulthood.
For mild to moderate relapse, such as crowded lower front teeth or a small gap reopening, Invisalign is often an excellent choice. Because the original braces did much of the work, treatment can often be shorter than a full course. Your dentist will assess whether your bite has also changed.
After a check-up and digital scan, your dentist plans the movements needed and shows you a simulation of the expected result. You then wear a series of aligners, usually for 20 to 22 hours a day, with check-ins to monitor progress.
The most important lesson from relapse is the importance of retainers. After treatment, you will likely need to wear a retainer at night long term. Fixed bonded retainers behind the front teeth are another option for some patients.
If your teeth have shifted because of gum disease, bone loss or missing teeth, these problems must be treated first. Your dentist will check your gum health before starting any orthodontic treatment.
Relapse is one of the most common reasons adults seek orthodontic treatment for a second time. Many people were given retainers as teenagers but stopped wearing them after a year or two, often because nobody explained that retention needs to be long term. Others had fixed retainers that came loose or broke and were never repaired. Lower front teeth are the most frequent area for relapse, followed by small gaps and rotations in the upper front teeth. If you notice changes, it is better to act early, because small movements are usually quicker and simpler to correct than more severe crowding that has developed over many years.
Before starting aligners, your dentist will check more than just the position of your front teeth. Bite changes, worn teeth, gum recession and bone levels all influence the treatment plan. If teeth have moved because of gum disease, aligner treatment must wait until the gums are healthy and stable, otherwise moving teeth could cause further damage. If you grind or clench, your dentist may plan the treatment to reduce excess forces. X-rays and a thorough gum examination ensure that your second orthodontic treatment is safe and that the result will be stable, rather than simply straightening the front teeth again.
After your aligners are complete, you will discuss retention options. Removable clear retainers are easy to clean and can double as whitening trays in some cases, but they only work when worn. Fixed retainers, thin wires bonded behind the front teeth, work continuously but need careful cleaning and regular checks to ensure they have not loosened. Many people choose a combination: a fixed retainer behind the lower front teeth and a removable retainer at night for the upper teeth. Whatever you choose, think of retention as lifelong. Keeping your retainers in good condition and replacing them when worn is far easier than repeating treatment.
Yes, in many cases. Invisalign is often well suited to correcting mild to moderate relapse.
Often yes, especially if only a few teeth have moved. The exact time depends on how much correction is needed.
Wear your retainer as instructed after treatment, usually every night long term.
