Many people experience temporary tooth sensitivity after a dental cleaning, but when that sensitivity lingers for weeks, it's cause for concern. This isn't uncommon, and understanding the reasons behind prolonged sensitivity can help you manage it effectively. This article will explore the potential causes and offer solutions to alleviate discomfort and promote healthy teeth and gums.
Why Are My Teeth Still Sensitive Weeks After a Cleaning?
This is a common question following a dental cleaning. Several factors can contribute to prolonged tooth sensitivity:
Aggressive Cleaning or Deep Cleaning:
A deep cleaning (scaling and root planing) is more invasive than a routine cleaning. The procedure removes tartar and plaque from below the gum line, potentially exposing sensitive tooth roots. Aggressive brushing and flossing techniques by either the patient or the dental hygienist can also irritate the dentin, the layer beneath the enamel that contains microscopic tubules leading to the nerve.
Gum Recession:
Gum recession exposes the roots of your teeth, making them more susceptible to sensitivity. This can be caused by various factors, including aggressive brushing, gum disease (periodontitis), genetics, and even grinding or clenching your teeth.
Worn Enamel:
Over time, enamel can wear down due to acidic foods and drinks, aggressive brushing, or teeth grinding/clenching. This exposes the dentin, leading to increased sensitivity.
Newly Exposed Dentin:
Even a routine cleaning can sometimes expose dentin, especially if you have gum recession or thin enamel. This exposure leads to heightened sensitivity to temperature changes and certain foods.
Cracked Tooth or Filling:
Sometimes, sensitivity that persists after a cleaning signals a more significant problem, such as a cracked tooth or a leaky filling. These allow irritants to reach the nerve, causing persistent pain.
Dry Mouth (Xerostomia):
Saliva plays a crucial role in protecting your teeth. Dry mouth, resulting from certain medications or medical conditions, can increase sensitivity as saliva normally neutralizes acids and lubricates the teeth.
What Can I Do About Persistent Tooth Sensitivity?
If your tooth sensitivity persists for more than a week or two after a cleaning, it's crucial to contact your dentist. They can diagnose the underlying cause and recommend appropriate treatment. In the meantime, here are some things you can try:
Use a Desensitizing Toothpaste:
Desensitizing toothpastes contain ingredients like potassium nitrate or strontium chloride that help block the tubules in the dentin, reducing sensitivity. Use these as directed.
Avoid Irritants:
Temporarily avoid hot, cold, acidic, and sugary foods and drinks. These can exacerbate sensitivity.
Gentle Brushing Technique:
Use a soft-bristled toothbrush and brush gently using short strokes. Avoid aggressive scrubbing.
Proper Flossing Technique:
Floss gently to avoid irritating your gums.
Fluoride Treatment:
Fluoride strengthens tooth enamel and can help reduce sensitivity. Your dentist may recommend a fluoride treatment.
When Should I See a Dentist About Persistent Tooth Sensitivity?
You should schedule an appointment with your dentist if:
- Sensitivity lasts longer than two weeks after a cleaning.
- Sensitivity is severe or accompanied by pain.
- You notice gum recession.
- You suspect a cracked tooth or damaged filling.
Don't ignore persistent tooth sensitivity. Early diagnosis and treatment can prevent more significant problems and alleviate your discomfort. Your dentist can accurately determine the cause and provide a personalized solution.
Are There Long-Term Solutions for Tooth Sensitivity?
Depending on the underlying cause, long-term solutions may include:
- Professional fluoride treatments: These can strengthen enamel and reduce sensitivity.
- Bonding: This procedure covers exposed dentin, protecting it from irritants.
- Gum grafts: If gum recession is causing sensitivity, a gum graft can restore gum tissue.
- Root canal: If the nerve is affected, a root canal may be necessary.
