A gap between the two front teeth, called a diastema, is one of the most common reasons people ask about smile treatment. There are three main ways to close it. The right one depends on why the gap is there, how big it is, and what the rest of your smile looks like.

Why do gaps form?

Some gaps are genetic: the teeth are slightly small for the jaw. Others come from a thick band of gum (the frenum) between the front teeth, a missing or small side tooth, a tongue-thrust habit, or gum disease letting the teeth drift. If a gap has appeared or widened in adulthood, have your gums checked first, because closing a gap without treating the cause usually fails.

Option 1: Invisalign or braces

Orthodontic treatment moves your own teeth together, so nothing is added to them. It suits gaps of almost any size, especially when there are gaps elsewhere or the bite needs correcting too. A single gap can sometimes close in a few months. You will need a retainer afterwards to stop it reopening.

Option 2: Composite bonding

Tooth-coloured composite is added to the sides of the teeth, usually in one visit with no drilling. It suits small gaps on teeth that are otherwise a good shape and colour. Composite can stain or chip over the years, and closing a large gap this way can make teeth look too wide. Bonding typically starts from about ₹4,000 per tooth.

Option 3: Porcelain veneers

Thin porcelain shells reshape the front of the teeth. They suit people who also want to change the colour, shape or length of their teeth. Veneers need some preparation of the tooth surface and are a long-term commitment, so they are rarely the first choice for a gap alone. Porcelain veneers typically start from about ₹16,000 per tooth.

Can the options be combined?

Often, and that frequently gives the most natural result: a short course of aligners to bring the teeth into a better position, followed by small bonding or veneers to perfect the shape. Moving teeth first usually means less needs to be added afterwards.

How to choose

Ask for an assessment that looks at the gums, the bite and the appearance together, ideally with a 3D scan, before deciding on any option.
