If you're wearing a Snap-On Smile, you can generally eat normally, although certain hard or difficult-to-chew foods may be a challenge. After your permanent veneers are placed, however, it's important to make changes to your diet in order to protect them. Avoid dark liquids such as black tea, black coffee, and red wine, and use a straw to reduce contact with your teeth. Hard or crunchy foods should also be avoided, as well as alcohol, which can damage the bonding material.
If you have sensitive teeth, it's best to stay away from extremely cold or hot food and drinks. When it comes to plastic veneers, you can still eat with them, but it's best to stick to hard, crunchy, and hot foods. You should also avoid anything that could stain your teeth, such as coffee. If possible, remove the veneer clip before eating.
