Hi..only if you are concerned about looks with braces then you need to think about lingual braces or Invisalign. First you need to understand that Invisalign is a brand and that treatment is called as aligners. You have different brands option other than Invisalign which can give you same treatment at lesser cost. There are many things to discuss before you go for any orthodontic treatment. Please visit my clinic in Pune for free consultation.

All type of braces have same action on teeth movement..lingual braces n invasalign r  esthetic wise good.. Lingual braces may some times causes tongue ulcers..

cost for lingual braces will range between Rs.80,000 to Rs.1,00,000. Cost of invisalign will be higher,about 2.5 lakhs....but nowadays clear aligners are available at much lower cost(around 1 lakh). The main disadvantage of lingual braces would be discomfort levels are higher.The most effective(faster) braces would be self ligating braces. There can be no guarantees as there are certain rare conditions where the tooth/teeth are stuck to the underlying bone(ankylosis).In this situation braces will not move the teeth.

Implanting lingual braces and Invisalign will cost around 1 to 1.6 lakhs. Only esthetics is the advantage of lingual braces. Its better to go for invisilagn if u have esthetics concern. All braces are effective what matters is the amount and the esthetics concern.u should confrm from ur orthodontist whether that gap will be filled or not

Cost of lingual braces and invisalign is depends on place to place but roughly 1-1.3 lac INR, AESTHETIC is the only difference in conventional vs lingual. Definitely but you have wear retainer honestly ti avoid relapse
