first and foremost important in senario is that gap has developed due to extraction of first molar as quoted in your  question yeah your concern is correct on invisible braces it will defenately close back that gap and regain the space of extracted first molar so advise is go for invisible treatment for closure of gap and regain of 1 st molar space and get implant in molar region ..it will be permanent solution cost of invisiliner  will depend on time required for gap closure ..wch is determined only after analysis

U need to go for replacement of the tooth by a dental implant. It is not possible to close a missing tooth gap by invisible braces. There is no such treatment option available. Do not try to use your own brain, consult a dentist for the same. Moreover, you will end up spending lakhs of rupees to do invisible braces without satisfactory results, whereas in a few thousands, u can get a new tooth.

This treatment option is not at all valid You are in need to get your first molar replaced by an artificial tooth that can aid in chewing. A implant or a bridge is advisable after all you are jus 21

Hi,where is the need to go for braces,instead you should get replacement of tooth by bridge or an implant.

Not really a good advice... Better to go in for dental implants 🙏🙏
