If you are having a dental crown placed, your dentist will put in a temporary crown to protect your tooth while the permanent crown is being made.
But you know—how long does a temporary crown last? Or curious about what you’ll do if you hold on to it too long or if it starts hurting? Not sure how to care for it? Read on to find the answers to all your questions.
What Is a Temporary Crown & Why Do You Need One?
A temporary crown is a short-term protective cover placed over a tooth while you wait for a permanent crown. It serves three main purposes:
- Shields the tooth from damage or infection
- Reduces sensitivity
- Maintains the appearance of your smile
Unlike permanent crowns, which are made of porcelain, ceramic, or metal, temporary crowns are crafted from acrylic or stainless steel. These materials are less durable, as the crown is meant to last only for a few weeks.
Your dentist will place a temporary crown if your tooth has undergone:
- A root canal
- A large filling that weakens the tooth
- A crack or break needing additional support
Without a temporary crown, the tooth could shift out of place, become overly sensitive, or even get infected before your permanent crown is ready.
How Long Does a Temporary Crown Last?
A temporary crown generally remains for one to three weeks. The exact duration will depend on the dental procedure and the healing time.
For example:
- Placing a conventional crown — 2 weeks
- Post root canal treatment — 3 weeks+
- Treatment of gum or bone — A few months in some cases
Temporary crowns aren’t as strong as permanent crowns, so they shouldn’t be worn for too long. The longer you delay your permanent crown, the higher the risk of damaging something or something complicated.
Can a Temporary Crown Last Longer Than Expected?
Yes, some people have a temporary crown for months or, in some cases, even a year. This is due to:
- Delays in crown production
- Insurance or financial issues
- Additional dental procedures needed
Although temporary crowns can last longer than expected, this is not good. The longer they stay in place, the higher the risk of complications.
If your temporary crown has been in place for more than six weeks, ask your doctor if it needs to be replaced or reinforced.
What Happens If You Keep a Temporary Crown for Too Long?
it may not sound like a significant issue, but it can cause multiple dental issues after some time.
1. Tooth Decay
Temporary crowns aren’t sealed as tightly as permanent ones. Over time, the cement that holds them in place weakens, allowing bacteria to enter. This can lead to tooth decay under the crown, which may go unnoticed until it causes:
- Sensitivity to hot or cold
- Dark patches around the crown
- Pain when chewing
Worst-case scenario? The decay continues, and you might eventually need a root canal before you can get your permanent crown.
2. Gum Irritation and Infection
Initially, a temp crown seems perfectly normal. But in the long run, it can irritate your gums, leading to:
- Swelling and redness
- Tenderness while eating
- Gums that bleed when you brush or floss
If this irritation is not treated, it can develop into an infection. In extreme cases, it may cause gingivitis or periodontal disease, requiring deep cleaning or antibiotics.
While pain near the crown is expected, irritation can sometimes cause discomfort in unexpected areas, such as the roof of the mouth. Identifying the root cause can help ensure proper treatment.
3. Breakage or Loosening
Since temporary crowns are made from acrylic or resin, they are not very durable. The longer they stay in place, the higher the chances of:
- Cracking – The material may wear down and break
- Becoming loose – Weak cement may cause the crown to shift
- Falling off – Your tooth is left completely unprotected
What to Do If Your Temporary Crown Falls Off:
- Try replacing it yourself using denture adhesive or toothpaste
- Avoid chewing on that side
- Schedule an appointment with your dentist ASAP
4. Bite Misalignment
Did you know your teeth are constantly moving? If a temporary crown is left in place for too long, the surrounding teeth may shift slightly, leading to:
- Uneven bite pressure
- Jaw pain or headaches
- Difficulty fitting the permanent crown
If your bite starts feeling “off” or uncomfortable, let your dentist know immediately. The sooner it’s corrected, the easier it is to fix!
How Is a Temporary Crown Removed and Replaced?
Receiving a dental crown typically requires two appointments. During the first visit, the dentist will prepare your tooth and fit a temporary crown, while the second appointment is when the permanent crown is placed.
Step 1: Removing the Temporary Crown
Your dentist will use specialized tools to gently loosen and lift the temporary crown. Since it’s held in place with a weaker, temporary cement, it usually comes off without much resistance. This step is typically painless, and numbing isn’t required.
Step 2: Cleaning the Tooth
Once the temporary crown is removed, the dentist cleans any remaining cement or debris from your tooth. This ensures a smooth surface for the permanent crown to fit securely.
Step 3: Fitting the Permanent Crown
The new crown is carefully placed over your tooth. Your dentist will check:
- Alignment – Ensuring the crown fits comfortably in your bite.
- Shape & Size – Making sure it blends naturally with your other teeth.
- Comfort – Adjusting if necessary to prevent discomfort or bite issues.
Step 4: Securing the Permanent Crown
Once the perfect fit is achieved, the crown is bonded with strong dental cement. This ensures it stays firmly in place for years to come.
The whole process takes about 30–60 minutes total, so you can go back to your daily routine with your new smile restored!
The Importance of Follow-Up Appointments
Don’t skip your second appointment to get your permanent crown. Temporary crowns aren’t meant to last long, and delaying the final placement can cause:
- When teeth shift, your permanent crown won’t fit properly
- Decay/infection under the temporary crown
- Heightened sensitivity and pain
How Do You Care For a Temporary Crown: Dos and don’ts
As highlighted above, it’s not as strong as the final crown, so you’ll have to be extra careful to preserve it. Taking a little time and attention now will save discomfort later, and result in a much more successful final restoration.
Dos and Don’ts
Do:
- Brush your teeth gently, especially around the crown.
- Floss carefully—slide the floss out instead of pulling it up to avoid dislodging the crown.
- Rinse with salt water if your gums feel sore.
Don’t:
- Eat sticky foods like caramel or chewing gum, as they can pull the crown off.
- Chew on hard foods like nuts or ice, which can crack the temporary crown.
- Use an electric toothbrush on the crown area, as the vibrations can loosen it.
Preventing Damage While Waiting for the Permanent Crown
- Chew on the opposite side – This reduces pressure on the temporary crown.
- Avoid grinding your teeth – If you have a habit of grinding, ask your dentist about a night guard.
- Stay on top of oral hygiene – Keeping your mouth clean prevents bacteria from affecting the tooth under the temporary crown.
Last Words
Temporary crowns play a crucial role in protecting your teeth between dental procedures. While they’re not as durable as permanent crowns, proper care can help them stay in place without issues. Follow your dentist’s instructions, avoid harmful foods, and maintain good oral hygiene to ensure a smooth transition to your permanent crown.
If you have concerns about your temporary crown, don’t hesitate to contact your dentist for guidance. Taking proactive steps now will ensure a healthier, long-lasting smile!
