Which tooth gem size should I choose?

The right tooth gem size depends on the size and shape of the tooth, the desired look and the position of the crystal.

For round tooth gems, X-treme Smile uses this practical size guide:

• XXS – SS2: approx. 0.90–1.00 mm
• XS – SS3: approx. 1.00–1.30 mm
• S – SS4: approx. 1.30–1.60 mm
• M – SS5: approx. 1.60–1.80 mm
• L – SS6: approx. 1.80–2.10 mm
• XL – SS7: approx. 2.10–2.30 mm

Why do we use a size range rather than one exact diameter?

SS2, SS3, SS4 and the other SS sizes are standardised size designations, but this does not mean that every individual crystal has exactly the same diameter.

Small variations can occur due to the manufacturer, brand, cut, faceting, material, production tolerances and differences between product ranges.

An SS5 from one brand may therefore be fractionally larger or smaller than an SS5 from another brand. Very small differences can even occur within the same production range.

For this reason, we deliberately provide an approximate diameter range and combine this with the easier XXS to XL system.

Why do we use XXS to XL?

SS sizing originates from the crystal and jewelry industry and can be difficult for clients to visualise. XXS, XS, S, M, L and XL provide a much more intuitive indication of how large a tooth gem will appear.

XXS and XS provide a very subtle sparkle and are ideal for multi-gem designs.

S and M are popular all-round sizes.

L and XL create a much more noticeable effect.

The same size can look very different depending on tooth size. An SS5 may appear subtle on a large front tooth but quite prominent on a smaller tooth.

Also consider the bite and placement. As a gem becomes larger, there is more surface that can potentially be contacted during biting and eating. Larger gems may therefore be exposed to more mechanical loading from foods such as hard fruit, carrots or crusty bread.

These measurements are guidelines for round tooth gems. Hearts, stars, drops, gold dental jewelry and other shapes are measured differently and cannot always be compared directly using SS sizing.
