What’s the Difference Between a Filling & a Crown?
You’re sitting in the dentist’s chair when you’re told you need a restorative treatment. Both fillings and crowns can fix damaged teeth, but they work in different ways and solve different problems.
A filling repairs small areas of decay by replacing the damaged tooth material, while a crown covers and protects an entire tooth when the damage is too extensive for a simple filling.
At Genesis Dental, many crowns for back teeth can be completed in a single visit using same-day crown technology.
When Your Dentist Recommends a Filling
Your dentist can spot small cavities during regular checkups, often before you feel any discomfort. When decay affects less than half of your tooth, a filling usually provides the right solution.
The filling procedure happens quickly during your regular dental visit. Your dentist removes the decayed portion and fills the space with tooth-coloured material that blends with your natural teeth.
Most of your original tooth structure stays intact with a filling. You keep your tooth’s natural strength while protecting the area where decay tried to take hold.
When You Might Need a Crown Instead
Large cavities that affect more than half of your tooth need stronger protection than a filling can provide. When decay spreads across multiple surfaces or reaches deep into the tooth, a crown often becomes necessary.
Cracked or broken teeth can also benefit from crown treatment. The crown acts like a helmet, holding all the pieces together and preventing further damage when you bite and chew.
After root canal treatment, your tooth becomes more fragile and needs extra protection. A crown is needed to restore the tooth’s original strength and help it function normally for years to come.
How Each Treatment Works
The Filling Process
Your dentist starts by numbing the area around your tooth. They carefully remove all decay and thoroughly clean the space.
Next, they fill the cleaned area with composite resin material that matches your tooth colour. The material bonds directly to your natural tooth structure.
Finally, they shape and polish the filling so it feels comfortable when you bite down. The entire process usually takes 30 to 60 minutes.
The Crown Process
Crown treatment looks a little different depending on the tooth being treated and the type of restoration you need. For most posterior, or back, teeth, Genesis Dental offers same-day crowns using in-office digital technology.
Your dentist removes the damaged portions of the tooth, shapes it for the crown, and takes a digital scan. The crown can then be designed and created right in the office, allowing you to leave with your permanent crown in a single visit when same-day treatment is appropriate.
In some cases, such as front teeth or more complex restorations, a traditional lab-made crown may still be recommended. If that’s the case, your dentist will explain the process and let you know what to expect.
Cost & Longevity Factors to Consider
Fillings typically cost less upfront and work well for minor tooth damage. You can expect a good filling to last 7 to 10 years with proper care.
Crowns require a larger investment initially but provide longer-term protection for damaged teeth. A well-made crown can last 15 to 20 years or more.
Insurance coverage varies by treatment type and your specific plan. Many plans cover fillings completely and pay a portion of crown costs when the treatment is necessary, rather than cosmetic.
Caring for Your Dental Work After Treatment
Regular teeth cleaning appointments help maintain both fillings and crowns. Professional cleanings remove plaque buildup that your daily brushing might miss.
Avoid chewing ice or hard candy, and avoid using your teeth to open packages. These habits can crack or loosen both fillings and crowns, leading to additional dental work.
Daily brushing and flossing protect the teeth around your dental work. Decay can still develop in other areas of the same tooth or in neighbouring teeth without proper home care.
