| For optimum protection it is advisable to check the surfaces regularly and to touch-up damaged places. |
| Those who avoid foods and beverages that stain may be able to wait one year or longer before another whitening treatment or touch-up is needed. |
| Every few years I run in for a little touch-up here and there, so I don't have to have a complete overhaul. |
| Humans aren't the only creatures who benefit from a touch-up. |
| Pack a touch-up kit containing mini versions of your favourite cosmetic products. |
| We are continuing to record live concerts and finish with touch-up sessions. |
