Do You Have a Hidden Cavity Between Your Teeth?

According to the Centers for Disease Control and Prevention, about 90% of adults aged 20 and older have had at least one cavity. They also report that 1 in 4 adults aged 20 to 64 currently has at least one in their mouth. So, as you can see, tooth decay is not an uncommon condition, including between your pearly whites! Here’s how to know if you have a cavity between your teeth and the next steps to take in order to restore your smile.

How To Know When You Have a Cavity Between Teeth

When decay occurs between your pearly whites, it’s called an interproximal cavity. Generally, you will be completely unaware that you have a cavity unless one of the following events occurs:

  • You begin to experience sensitivity to cold or hot temperatures due to the cavity penetrating the enamel and reaching the second layer of tissue of your tooth called dentin.
  • Your dentist or hygienist discovers the cavity, usually found in an X-Ray.
  • You are suffering from a toothache.
  • You notice discoloration of your teeth around the infected area.
  • You feel pain when chewing your food.

Your Next Steps…

If you have an interproximal cavity, there is no need to stress! Your dentist can get your oral health back on track. Treatment will vary depending on the extent of the decay. These could include:

  • A dental filling: A tooth-colored filling can be used if the cavity has spread to more than halfway into the enamel. It will restore the tooth to its normal shape and function.
  • Getting a crown placed: For more advanced decay, a dental crown can be placed over the entire visible portion of your tooth. This provides future strength and protection, while still appearing like your natural smile.
  • A root canal: Severe cavities root canal therapy, which deeply cleans out the infected tissue, while using special biocompatible material to fill and strengthen your tooth.
  • A tooth extraction: If the tooth is too damaged, it may need to be removed to prevent infection, as well as alleviate pain. Your smile can then be completed with a bridge, dental implant, or partial denture.

How Can You Prevent Cavities?

Fortunately, most dental decay can be completely prevented with a few consistent practices! By brushing your teeth twice a day and flossing at least once daily, you are cleaning your teeth and gums from harmful bacteria and plaque. These routines are key for protecting yourself from an interproximal cavity. Finally, it is essential to visit your dentist twice a year for a checkup and cleaning. This allows your dental team to catch any dental problems early on before it advances into something more serious. Additionally, by having tartar buildup removed from your teeth in the hard-to-reach areas of your mouth, you are protecting your smile from cavities forming in the first place!

I've been coming to this practice for years now since moving to the Raleigh area. The office is always clean and organized and the staff have always been friendly and communicative. Also, the TV's mounted to the ceiling are a nice touch! I've been seeing Dr. Laster for several years before our insurance changed causing me to change to Dr. Rensch. Both are so easy to talk to and always made me feel at ease.

From beginning to end 5/5! I thought I was experiencing a dental 911. I submitted an inquiry at 11:30pm and by 8am the next morning, Deidra (front office staff) was already leaving me a message. She was so sweet and patient at 8am lol. After our initial conversation, I informed all follow up dentists “I found my dentist office” but thank you so much! Today I was welcomed with the same energy from Diedre to Britany then finally Dr.Wrench. The music playing throughout the office was fantastic; ie music selection and volume. The TV’s on the ceiling and wall made my procedure so painless and enjoyable! I watched an entire Christmas movie lol! Dr. Wrench (apologies for spelling) made my teeth absolutely perfect! I left telling my friends and family I have a million dollar smile! 😊 I can tell he wanted them perfect and he did! Thank you all so much for being amazing! Sincerely, Your next patient.

Dr. Laster and Dr. Rensch go above and beyond for their patients. I have seen both for various treatments and I always feel comfortable and heard. They take time to listen and to talk with you. They explain your options and work with you to develop the best plan for your care. They are always upbeat and positive and you can tell they truly love what they do. The front desk staff is exceptional as well. Deidre is so caring and very sweet. She’s efficient, understanding and conscientious of your time. I highly recommend.

Connections Dentistry was great! The staff is so friendly and truly cares about their patients. My appointment was quick, and honestly the best dental experience I’ve had. They are great about offering helpful solutions without making you feel like you are being reprimanded… which was the reason I was putting off the dentist. 100% recommend!
