Jawline Exerciser — Silicone Chew Ball, 2 Pack

A firm silicone ball you chew against to work the masseter — the muscle that runs up the side of the jaw. Sold in twos, so you can work both sides evenly.

What you get

• Two per pack — one for each side.
• Food-grade silicone — firm enough to give resistance, soft enough not to crack a tooth.
• White, black or grey.

Worth knowing before you buy

An honest note, because these are marketed heavily and often dishonestly. Training the masseter can add a little muscle definition along the jaw. It cannot change your bone structure, and it will not remove fat under the chin — nothing you chew can do that. Overdoing it can also aggravate jaw joint pain, so build up slowly and stop if it clicks or aches.
