There are many reasons for this to happen. A proper diagnosis can only be made by a dentist by doing a clinical exam with xrays. Make the call. In the mean time avoid cold food and drink. Brush with warm water.
Most likely recession along those teeth, meaning the gum has shrunk away from the teeth. Most obvious way of knowing this is if the teeth look longer.
There are many possible answers to this question.
Your best answer would be from your dentist after an examination.
A few possible answers:
That is just the way it is right now, and with time the sensitivity will disappear
Clenching and or grinding of the teeth, especially during sleep
Using drinks that have a low Ph. (This includes all sodas, sports drinks, many of the bottled water drinks, fruit drinks, fruit juices, and similar.)
You have recently had treatment for gum disease
You are using a strong bleaching solution to whiten your teeth
Other reasons
Your best information will come after an examination and consultation with your dentist.
Gum recession & grinding sometimes causes sensitivity. Look for those signs and see a dentist for a consultation.

There are so many possible causes. Do visit your dentist. I am sure sure he will give you some answers. Some of the possibilities include gum recession, abfractions exposing the underlying dentin, erosion due to acid, bruxism, and clenching.
Hope this helps.
If you see the edge of the teeth very flat, it could indicate grinding (Bruxism). If so, you may experience frequent headaches as well and tire when chewing gum. Whitening toothpastes may also increase or cause sensitivity as well.
One of the reasons could be gum recession. When the gum recedes, part of the tooth’s root surface will be uncovered, therefore you feel sensitivity.
Most likely cause is tooth grinding, or could be you have receding gums.
There are several factors which can cause teeth to become sensitive. The most common reasons are gingivitis (inflammation of the gums), plaque and calculus induced decaying tooth surface, and exposure of the root surface of the teeth. I believe it would be best that you make a quick visit to the dentist and get it evaluated.
This is a very common issue, but the solution depends mostly on the cause of the problem. Therefore, before we know how to deal with the problem, first we need to know what’s causing painful sensations related to cold, heat, or sweet foods and drinks.

Could be several possibilities: Root sensitivity would be my first guess, but you must see your dentist and let them diagnose the problem
Since you have described a general area which includes the lower jaw entirely, it makes me think that you may have excessive bruxism from stress. If you grind your teeth unknowingly while you sleep, the amount of attrition that occurs or loss of animal would cause generalized sensitivity in the lower teeth because there is not as much to structure in mass on the lower teeth in general as there are on the upper teeth. If you are grinding your teeth unknowingly, you need a night guard. But first, you need to be examined by a dentist to confirm both by oral examination and X-rays that this is nothing that's pathologic.
The number one most common reason for sensitivity is recession of gums. This is very typical, especially with people who are adamant about good oral hygiene and scrub their teeth and gums hard. Try a toothpaste for sensitive teeth and brush more gently!
There are many factors that can attribute to sensitivity. Some are caused by worn enamel due to excessive brushing or gum recession. You may clench or grind your teeth that have caused the sensitivity. Or you many need dental treatment for any carries that you may have. Only with a comprehensive examination and X-rays can you get a better understanding of what may be your cause of discomfort.
If you have whitening in your toothpaste that can cause your teeth to be sensitive.
The causes of sensitivity are very broad. The best way to begin to find the answer is to schedule yourself for a complete dental examination to zero in on the possibilities. Some possibilities include clenching/grinding, erosion, dental infection of the nerves of the teeth, or even an incorrect bite. They are all very different, but they also could lead to the same symptoms of sensitivity as an end result.
There area a number of possible reasons. Some that come to mind include gingivitis, periodontitis, tooth decay, and others. I would recommend making an appointment with your dentist.

The reason is mainly thin enamel, which can be due to use of a hard brush, or our eating habits, i.e., too much acid in the food, grinding our teeth or systemic problems like acid reflux of our stomach. In your case, I think you are grinding you teeth so your lower teeth have abrasion, loss of enamel their for sensitivity. I think if you start using a night guard, it will help you.
There are many possibilities for this. Night time clenching or grinding- known as bruxism could be one of the reasons. Also if you’re using a toothpaste that is too abrasive this could be part of the answer. Best you see a dentist for assistance with diagnosis and treatment.
Could be from grinding your teeth at night. Or from root exposure.

Different things may cause teeth sensitivity. In kids, around the age of 7-11, since the permanent teeth are erupting the nerves inside the teeth are fairly large; therefore, the teeth are more sensitive. Early cavity detection is very important for that reason as caries (cavities) reach the nerve fairly fast.
In adults, generally, as we age, we tend to lose bone density, especially around the front teeth, so the roots of the teeth feel the temperature changes more. Also, gum recession causes more root exposure, be mindful that roots don’t have the enamel layer which is the protective shield for the coronal portion of the tooth. Roots of the teeth are more sensitive to heat and cold. Several things can cause gum recession:

-Gum disease
-Hard brushing
-Grinding your teeth
-Restorations that are too close to the bone level
-Bone loss

You need to have a clinical exam to determine what is the reason for your teeth sensitivity and receive the proper treatment.

You may have recession, where your gums have moved away from your tooth due to aggressive brushing, clinching your teeth, eating acidic foots, etc. This is very common. Try using sensodyne toothpaste twice a day to reduce the sensitivity.
Perhaps your gums are receding from overzealous toothbrushing or you might have cavities. A diagnostic X-ray would be helpful to rule out an abscess from decay or trauma. Please contact a dentist if Sensodyne or other desensitizing toothpastes fail to alleviate your discomfort.
Sensitivity on the lower teeth may have many causes. The most likely cause is that you are in hyper occlusion or there is premature contact between these teeth and the opposing uppers. This can be corrected by a minor bite adjustment.
Since it is all teeth, it's unlikely that all of your teeth are decayed. Gingival recession is a very common cause of sensitivity. Try a desensitizing toothpaste like Sensodyne to start. Avoid acids in the diet and brush carefully up and down, not back and forth.
Sensitivity of teeth have various reasons. Gum recession can be one of them. Also decay/cavities can cause sensitivity. Please see your general dentist.
You may be ingesting an acidogenic diet that demineralizes the enamel on your teeth, exposing the sensitive dentine.
This can be due to several issues. It's best to have your local dentist assess you properly.
If it's along the gum line, most likely due to recession. If nor could be an issue with grinding of your teeth
Often what causes generalized sensitivity is either a mouth with multiple fillings or recession of the gums exposing the tooth roots. Additionally grinding your teeth or clenching can progress sensitivity. Sensodyne toothpaste or MI Paste One with exam from dentist is recommended.
Several things can cause your teeth to be sensitive including grinding, acid erosion (from acid reflex) and decay. I recommend you see a dentist for a cleaning and evaluation.
Some people have naturally more sensitive teeth. Try Sensodyne toothpaste. It works really well. Also ask your dentist about president (a prescription tooth paste with extra fluoride).
Sensitivity can be a result of many causes; however the most common cause is a disharmony in your occlusion or 'bite'. Have your occlusion checked by a dentist and if there are any interferences to the ideal bite, the dentist can gently polish them away. The sensitivity should subside within a day or two.
