If you need a cavity repaired, your dentist will likely recommend a composite, or tooth-colored, filling. Though some dentists still place metal fillings, most providers have switched to all-white fillings. Tinted to match your enamel, composite fillings blend with your smile. Learn more about the benefits of all-white fillings with this Q and A.
Why choose composite fillings over metal fillings?
The most obvious answer is appearance. All-white fillings won’t compromise your gorgeous smile. Another benefit of composite fillings is that they require less removal of healthy, tooth structure, allowing for more conservative restorations.
Will all-white fillings cause teeth sensitivity?
Unlike metal fillings, which conduct hot and cold, tooth-colored fillings won’t result in the discomfort of sensitive teeth. Composite fillings do not expand or contract either, so your filling won’t change shape over time.
Can you replace my old fillings?
Many people opt to remove metal fillings and replace them with composites for purely aesthetic reasons. If your old repair starts to crack or leak, you should definitely have the filling updated.
How do I know if I need a filling or crown?
Several factors influence this decision, including the amount of damage, size of damage, and strength of the tooth. Your dentist will select the smallest restoration possible while also renewing the health and stability of the tooth.
How long will composite fillings last?
The key to keeping these restorations in good shape is expert placement and good home care. Make sure you brush often, floss frequently, and see your dentist for checkups. With these steps, your new filling should last as long, or longer, than a metal filling.
