If you have only completed 6-7 months of your orthodontic treatment, it is generally not recommended to remove your braces before completing your treatment. This is because your teeth are still in the process of being repositioned and if you remove your braces too early, your teeth may not be in their proper positions and may need to be re-braced, which can prolong your treatment time and be more costly in the long run.
It is important to try to find an orthodontist in the UK who can continue your treatment before you leave. You may want to consider reaching out to your current orthodontist for recommendations or to see if they have any connections in the UK who may be able to take over your care. You can also try searching for orthodontists in the UK online and contacting them to see if they are able to take on new patients.
It is difficult to predict exactly how much your orthodontic treatment will cost in the UK without more information about your specific case. However, it is generally more expensive to receive orthodontic treatment in a country with a higher cost of living, such as the UK. In addition, if you need to start your treatment over with a new orthodontist, it may also be more expensive as you will need to go through the initial consultation and diagnostic process again.
In general, it is a good idea to try to continue your orthodontic treatment without interruptions if possible, as this can help ensure that your treatment is as efficient and effective as possible. If you are unable to find an orthodontist in the UK who is able to take over your care, you may want to consider delaying your trip until your treatment is completed or discussing alternative treatment options with your current orthodontist.
