If drinking cold water makes you wince or sipping hot tea sends a sharp pain through your mouth, you are not alone. Tooth sensitivity is one of the most common complaints dentists hear in Lagos, and while it is easy to dismiss it as something minor, it often points to something that needs attention.
This article explains what causes sensitive teeth, what treatment options are available, and what actually works beyond just switching your toothpaste.
What Tooth Sensitivity Actually Feels Like
The pain is usually sudden and sharp. It hits the moment your tooth makes contact with something cold, hot, sweet, or even sour, and then fades within seconds. That quick disappearance is what makes most people shrug it off. But if it keeps happening, the pattern matters.
Sensitivity is different from a regular toothache. A toothache tends to be persistent and localised. Sensitivity is triggered by something specific and tends to affect multiple teeth. However, when sensitivity is concentrated in one tooth and lasts longer than a few seconds after the trigger is removed, that is a different situation and deserves a closer look.
Why Your Teeth Become Sensitive
Your teeth are covered by enamel, the hardest substance in the human body. Beneath it is a layer called dentine, which contains thousands of tiny channels called dentinal tubules. These tubules connect to the nerve of the tooth. When enamel is intact and gums are healthy, these channels stay protected. When that protection is compromised, temperature changes, pressure, and sugar can travel through those channels and trigger the nerve, producing that familiar sharp sensation.
Here is what causes that protection to break down.
Your Enamel Has Worn Down
Enamel erosion is one of the most common causes of sensitivity, and diet plays a major role. Frequent consumption of carbonated drinks, citrus fruits, zobo, and other acidic foods (An article on list of acidic foods that should be avoided to protect your enamel)
gradually eats away at enamel over time. Brushing too hard or using a hard-bristled toothbrush speeds up the process.
Once enamel is gone, it does not grow back. The goal at that point becomes protecting what remains and sealing the exposed surface. You want to avoid this when you can.
Your Gums Have Pulled Back
Gum recession exposes the root surface of the tooth. Unlike the crown of the tooth, the root has no enamel covering it. It is protected only by a thinner material called cementum, which wears away more easily. Once the root is exposed, even cool air can cause discomfort.
Gum recession happens gradually, often without pain, which is why many people do not notice it until sensitivity begins. It can be caused by gum disease, aggressive brushing (Aggressive brushing and what it does to your oral health), or simply genetics.
A Cracked or Chipped Tooth
A crack in a tooth, even a hairline one you cannot see, creates a direct pathway for temperature and pressure to reach the nerve. This type of sensitivity often feels sharp and is usually localised to one tooth. Biting down on something hard, a bone in your meat, an unpopped kernel, or a tough chin-chin can cause this.
A cracked tooth will not heal on its own. Left untreated, the crack can deepen and eventually affect the nerve or cause the tooth to break.
Tooth Decay or a Leaking Filling
Cavities create openings in enamel that expose dentine to everything you eat and drink. Old or poorly sealed fillings can also develop gaps over time, allowing bacteria and temperature changes to reach the inner layers of the tooth.
If you have had a filling for several years and sensitivity has recently developed in that tooth, the filling may need to be replaced or the tooth assessed for new decay. It’s time you visit your dentist immediately.
Recent Dental Work
This is a cause of teeth sensitivity that you don’t have to worry about. This is because some sensitivity after dental procedures is completely normal. Teeth whitening, deep cleaning, and fillings can all cause temporary sensitivity that typically resolves within a few days to two weeks. If sensitivity continues beyond that window or worsens, it is worth going back to your dentist.
Teeth Grinding
Many people grind their teeth at night without realising it. Over time, grinding wears down the biting surfaces of teeth, thinning the enamel layer and gradually increasing sensitivity. If you wake up with jaw soreness, frequent headaches, or your partner has mentioned the sound, grinding could be contributing to your sensitivity.
This is particularly common among working professionals dealing with stress, and it tends to go unaddressed for a long time because the damage is slow and not immediately obvious. You can book a consultation today to address so we can talk about it and proffer a solution to it.
What Tooth Sensitivity Treatment Procedure is
The right treatment depends entirely on what is causing the sensitivity. This is why a diagnosis comes before any recommendation. There is no single fix that works for every case.
One: Desensitising Treatments Applied in the Clinic
For mild to moderate sensitivity caused by enamel erosion or exposed dentine, a dentist can apply a fluoride varnish or desensitising gel directly to the affected teeth. These treatments work by blocking the dentinal tubules, reducing the signal that reaches the nerve.
The application is quick, painless, and can provide meaningful relief. Depending on the severity, it may need to be repeated periodically.
Two: Dental Bonding for Exposed Roots or Worn Enamel
Where gum recession or enamel erosion has left a surface exposed, dental bonding uses a tooth-coloured resin material to cover and seal that area. It is a conservative, non-invasive procedure that can significantly reduce sensitivity while also improving the appearance of the affected tooth.
It does not require drilling and is completed in a single appointment in most cases. You can visit Dr reach Dental Clinic today, for a quick fix.
Three: Dental Fillings or Crown Replacement
If the sensitivity is coming from a cavity or a failing restoration, addressing that directly resolves the problem. A new dental filling seals the tooth properly. In cases where a tooth has significant damage, a dental crown may be recommended to fully protect it.
Putting this off tends to make the situation more complicated over time. If you stay in Lagos or close by, you can book a consultation with Dr. Reach Dental Clinic.
Four: Gum Grafting for Severe Gum Recession
In advanced cases where gum recession has exposed a significant portion of the root, a gum graft may be the most effective solution. This involves taking a small amount of tissue, usually from the palate, and using it to cover the exposed root surface.
It is a more involved procedure, but for patients with significant recession and persistent sensitivity, it offers lasting results.
Five: Root Canal Treatment
When sensitivity is severe, persistent, and linked to inflammation or infection of the nerve itself, a root canal treatment becomes necessary. This is not a first-line treatment for sensitivity. It is used when the nerve is involved and other options are no longer sufficient.
Also, it is also worth clarifying a persistent myth: root canal treatment relieves pain. It does not cause it. Most patients are surprised by how manageable the procedure is compared to what they expected.
Six: Night Guards for Grinding
If grinding is contributing to your sensitivity, a custom-fitted night guard protects your teeth from further enamel loss while you sleep. It does not reverse existing damage, but it stops the situation from getting worse and allows other treatments to hold.
How Much Does Tooth Sensitivity Treatment Cost in Lagos?
Treatment costs in Lagos vary depending on what is causing the sensitivity and what is needed to fix it. If all you need is Scaling and Polishing, 60k but if it’s dental implant, costing you at least 400k. A fluoride application or bonding procedure is also at a different price point than a crown or gum graft. The only way to get an accurate figure is after a proper clinical assessment.
What a consultation does is confirm exactly what the problem is, rule out anything more serious, and give you a clear treatment plan with associated costs upfront. That clarity is worth more than guessing based on symptoms alone.
Dr. Reach Dental Clinic offers consultations at both their Yaba and Ikeja locations, with a team that understands the specific dental concerns of Lagos patients.
Frequently Asked Questions
It depends on the cause. Sensitivity following a dental procedure often resolves on its own within two weeks. Sensitivity caused by enamel erosion, gum recession, or decay will not go away without treatment. In those cases, the condition typically worsens gradually if left unaddressed.
Most treatments for sensitivity are straightforward and well-tolerated. Fluoride varnish and bonding involve no drilling. Even procedures like fillings and night guard fittings are routine and manageable. Your dentist can discuss what to expect before any treatment begins.
For in-clinic desensitising treatments, some patients notice relief within a few days. Dental bonding provides more immediate results. For conditions like gum recession or decay, relief comes after the underlying problem is resolved, which varies by case.
Yes. Children can experience sensitivity, particularly as permanent teeth come through or if there is enamel thinning from acidic diets or frequent sweet drinks. It is worth having it assessed rather than assumed to be a normal part of growing up.
Whitening can increase sensitivity temporarily. If you already have sensitive teeth, it is important to tell your dentist before any whitening procedure. Professional whitening done under clinical supervision allows your dentist to take the necessary precautions, adjust the treatment, or treat the sensitivity first.
