Sorry to hear that your teeth has relapsed from your previous braces treatment.
Both conventional fixed braces and Invisalign are effective in moving and straightening teeth, regardless of whether it is for relapse or new cases.
Most relapse cases occurs with shifting of the multiple teeth rather than just one of two teeth, as teeth cooperates and function together. Hence, orthodontic treatment usually occurs on both arches together to ensure good functionality of teeth.
Conventional fixed braces have long-standing successful history in correcting misalignment of teeth, whereas Invisalign is comparatively new in the market (about 20~ odd years). However, Invisalign has gone through tremendous improvement over the years and is now able to achieve results which are higher in complexity and also achieve results in a shorter time frame, thanks to the huge database that they accumulated over a short period of time due to its high popularity.
As you have experienced before, fixed braces involve brackets that are glued to the teeth. In contrast, Invisalign is a mould of your teeth which can be removed anytime and anywhere.
Invisalign is more suitable for a patient when they need minimal disruption to their everyday lives (invisibility, better comfort, less ulceration, minimal disruption to eating habits etc.). However, do note that Invisalign recommends wearing their trays for 20-22 hours per day. Hence, good discipline entails.
Both methods require excellent dental hygiene as both increases the possibility of cavity and gum problems. In this aspect, patients with Invisalign would probably fare better as it is easier to clean the Invisalign trays and their teeth, compared to digging under the metal brackets for fixed braces.
On another note, invisalign offers Invisalign light, which is meant for correcting very minor misalignment of teeth, with a lower cost. However, this is on case to case basis, depending on suitability. Since your’s is a relapse case, you might enquire if you are suitable for this.
Ultimately, deciding which method is best for you requires you to have a consultation with your dentist, to find out the severity of your relapse and suitability of each option, personalized to you.
Hope this helps and good luck with your treatment.
