“Why are my teeth sensitive to cold?”

This is one of the most common conditions and complaints reported to me by patients. This is a rather ubiquitous problem shared by many people as evidenced by the plethora of dental products on the market catering to sensitive teeth, Sensodyne Toothpaste being the most readily recognized.
Cold sensitivity does not necessarily mean that you have a serious dental problem looming. But while the cause may be not be serious in nature, the noxious feeling brought on by something cold can be rather startling and severe. This is because the only sensation that the nerve of a tooth registers is pain. Regardless of the type of stimulus (hot, cold, sweet, etc.) if the dental nerve is agitated, it will hurt.
The intensity of cold sensitivity can run the spectrum from mild inconvenience to intense “stopped me in my tracks” pain. The purpose of this soliloquy on cold sensitivity is to identify the most common causes and offer some practical solutions.

8 Reasons That Teeth Are Sensitive To Cold

Plaque Build-Up And Gum Inflammation
Periodontal (gum) disease can be a cause of cold sensitivity whether in its earliest stages as Gingivitis, or more advanced. A build-up of bacterial plaque is not only potentially destructive to your gums and bone, which support your teeth; it is also an irritant, which can lower the threshold at which pain is perceived. In other words, the presence of bacterial plaque can actually make your teeth more sensitive.
I have seen more than a few patients with healthy mouths come into my office complaining of general cold sensitivity when all they need to resolve the issue is a gentle and thorough cleaning. Often times these are longstanding patients who are overdue for their periodic re-care visit. Additionally, the persistent presence of plaque can promote periodontal disease which can lead to gum recession.

Gum Recession
Receding or receded gums are common causes of cold sensitivity. When your gums are not firmly attached to a tooth, as in the case of gum disease, they can actually pull away from the tooth and creep down (or up if it’s an upper tooth) leaving exposed root surface. Unlike the normally exposed part of your tooth, the root does not have enamel protection and therefore is more reactive to temperature, especially cold.
Aggressive brushing with a hard-bristled toothbrush or excessive pressure when using an electric toothbrush can cause gum recession and the resultant cold sensitivity. As I have stated in previous postings, tooth brushing should be a gentle process that is confined to the tooth structure. Don’t scrub your gums, either. And always be mindful that you are not scouring bathroom tile! It is very easy to damage your gums and cause recession with improper brushing techniques. For tips on tooth brushing, link here: The Dos and Don’ts of Brushing Your Teeth.
Patients who have had periodontal surgery or orthodontic treatment may also have gum recession. Aside from proper brushing techniques, fluoride rinses (both over-the-counter and prescription strength) and desensitizing toothpaste can help decrease sensitivity over time.

Bruxism And Clenching
Grinding or clenching of one’s teeth are commonly referred to as parafunctional habits. Bruxing (grinding) and clenching teeth together can be a potentially destructive pattern of behavior in which tremendous forces are placed on your teeth. This can result in a loss of tooth structure on the biting surfaces (dentist’s call this occlusal wear) or near the gum-line (abfractures). As your tooth wears down, the sensitive dentin can be exposed, creating temperature sensitivity, especially to cold.
Because grinding and clenching can generate upwards of 500 lbs. per square inch of force, your teeth themselves can be so traumatized to make them more reactive to cold stimulus.
Aside from temperature sensitivity, bruxism and clenching can cause premature tooth loss, muscle tenderness and TMJ symptoms. Many people who clench or grind their teeth benefit from an occlusal nightguard, which protects the teeth from wear during sleep.

Tooth decay is one of the most common reasons that you may have a tooth that is sensitive to cold. In fact, cold sensitivity is one of the earliest symptoms of a cavity. Unlike the previous conditions, cold sensitivity due to a cavity is more localized and is restricted to the involved tooth. See your dentist!

Broken Teeth or Lost Fillings
For reasons similar to teeth that have cavities, if you have a tooth or teeth that are broken, cracked or if you have lost all or part of a filling, cold sensitivity can arise. Generally this heightened sensitivity is because part of your tooth’s structure is exposed. Sometimes, if a break is severe, the nerve can be exposed causing an actual toothache. Clearly in any of these situations, a visit to the dentist is warranted. Go!

Acidic Food and Beverages
Beware of the many beverages on the market promoted by their manufacturers to be healthy alternatives to other drinks, such as soda pop.  Many of these so-called vitamin waters, energy drinks, and sports drinks are highly acidic and if consumed in large quantities can cause your teeth’s structure to break down. Acidic drinks are caustic and can actually dissolve tooth structure much the same way acids from bacterial plaque cause cavities!
The problem lies in how often you consume the offending drinks and the amount of time they are allowed to linger in your mouth. It’s best not to swish a drink while consuming as it prolongs the acid attack on your teeth. Also, do not brush your teeth for at least 30 minutes after consumption because the “softened” enamel or dentin is more susceptible to abrasion. This also applies to foods such as citrus fruits, pickles and vinegar that also have low ph. values (acidic). For more on this issue, please see: Is your Favorite Beverage Eroding your Tooth Enamel?

Recent Dental Treatment
The placement of large restorations, fillings or crowns can also provoke sensitivity. Restorative dentistry is actually a kind of “bloodless surgery” but it’s surgery nonetheless. Vital tissue is cut, albeit with a dental drill and not a scalpel, and the nerve of your tooth can be traumatized and sensitized by it. It is not uncommon for a recently restored tooth to have cold sensitivity that can last for several days.
If the condition lingers beyond this time frame, you should revisit your dentist. Often a simple “bite adjustment” can resolve the issue, especially if the filling was a bit too high. But don’t wait. Delaying a needed refinement can prolong your recovery time. Sometimes a cleaning or scaling can lead to temporary cold sensitivity.
If you experience cold sensitivity after a routine cleaning at your dentist’s office, try to be patient. Plaque removal can sometimes expose root surfaces that were “protected” from the elements by the very plaque that needed to be removed.

Acute PulpitisAcute pulpitis is an inflammation of the dental nerve. Generally the symptoms of this condition are more severe than just slight cold sensitivity. Not only are the teeth especially responsive to cold, the pain lingers even after the stimulus is removed. The intensity of this condition often necessitates root canal therapy. If you are experiencing this…go to your dentist right now.

Cold sensitivity is often more of a quality of life issue than a progressive pathological process that will worsen over time. In other words, normally there is nothing seriously wrong. I use various treatment approaches including conservative over-the-counter remedies, fluoride prescriptions, desensitizing treatments, as well as more definitive dental procedures such as bonding or gum grafting (to name just two). The proper management of cold sensitivity depends on the cause, the severity and the duration.
If you experience cold sensitivity, speak to your dentist for advice. If you develop sudden cold sensitivity or any other type of severe sensitivity, make an appointment as soon as possible.

Various Amenities which makes Heart of any Dental Facility

Inside the X-Ray Room
 Our X-ray room is equipped with intra-oral x-ray, digital dental panaronic tomogram (OPG) and digital cephalometry x-ray.

State of the art of digital imaging system for diagnostic purposes.

 Digital Dental Panaromic Tomogram (OPG) 

Patient is positioned this way to take a OPG image

An example of a OPG image. The whole jaw can be seen including the sinus and nasal (nose) area. It is good for implant assessment and identifying pathological disease such jaw cyst.

Digital Cephalometry X-ray 

Position of the patient for cephalometry X-ray

An example of Lateral Cephalometry Image. This image is useful for orthodontic assessment. This image provide information of the jaw relationship and the growth pattern of the patient.  

Intra-oral Camera
A small camera is used to capture videos and images of the teeth and structure in the mouth during consultation or after treatment on a screen. Therefore, the patient can actually watch the condition of his/her teeth on screen. 

ZOOM 2!! Whitening System

This is the bleaching system that whiten your teeth in just ONE visit. No need to go home to do it. 
The moment you come out of our clinic after bleaching, you with experience whiter brighter smile... 

ZOOM 2 uses light to active the bleaching agent, resulting in whiter & brilliant teeth. This treatment is safe & effective (patient has to be checked and consulted before treatment) 

Air Flow -- Air Polishing System 
Scaling and polishing itself does not effectively remove staining which arise from smoking, coffee or tea.

With air polishing, stain can remove effectively by blasting sodium bicarbonate, water and air to tooth surface. This gentle jet stream  will remove the stain through light abrasion. Air polishing is used after scaling.

Gentle jet stream of sodium bicarbonate water and air from the Air Flow system.

This is the result after using air polishing. Teeth become whiter, smoother and clean. 

Bloodless way to do a surgery

Electrocautery is a surgical technique which involves introducing high frequency current to a specific area of the body in order to remove unwanted tissue, seal off blood vessels, or to create a surgical incision.
Simple surgical procedure can be done using electrocurtery, such as:
  • Crown lengthening 
  • Gingivectomy
  • Removing epulis, 
  • Biopsy
Advantages from electrocurtery:
  • Cleaner
  • Safer
  • Less bleeding
  • Fast healing
Crown lengthening procedure was done with a electrocurtery.

Implants Systems
We are using high quality implant system for our customer. All of this implant systems are well known and top leading in Malaysia as wellas in the world.

 Zimmer Surgical Kit and Implants

Implant 4.7x8mm from Zimmer

Osstem Surgical Kit

Sinus lift set - This set of instruments is used to open the sinus area through lateral windows technique to allowed implants to be place on the upper jaw with very thin alveolar bone verically.

SinusTech set - The latest innovative design of remears used to prepare implant site (internal sinus lift procedure) on bone without injuring or perforating the sinus membrane.

Apex Locator (For Root Canal Treatment)
It is a very useful electronic device to check and determine the length of the tooth during root canal therapy. This will reduce the amount of x-ray exposure to the patient during treatment; and cleaning of the root can be done properly.

Digital SLR Camera 
The important of capturing clinical picture in clinic:
  • For documentation
  • Diagnosis and treatment planning -- especially in the aesthetic region
  • To allow patient to see and appreciate the condition of his teeth
  • To compare before and after treatment -- especially for teeth whitening
  • To allow the laboratory technician to know the appearance of the patient and therefore able to fabricate  correct colour and shape of the prosthesis to the patient
  • To learn and  improve the skill and knowledge of the clinician/dentist
  • To be able to share with other researcher or dentist (in conference)

A digital single-lens reflex (SLR) camera is a camera that typically uses a semi-automatic moving mirror system that permits the photographer to see exactly what will be captured by the film or digital imaging system, as opposed to compact cameras where the view through the viewfinder could be significantly different from what was captured on film. Images taken from SLR camera are clearer and sharper as compared with compact camera.

However, in the mouth where the area of interest was small and dark, ordinary lens with internal flash are not enough to capture good quality pictures. Therefore, here, we are using the Nikon D90 camera with Nikon 105mm f/2.8 VR  micro lens together with a ring flash from Sigma. All of our pictures presented in this blog are taken with this camera!!
