Dental pain is NOT the ONLY symptom of Dental Diseases

Most people don't know that dental pain is not the only symptom of dental diseases. Even we dentists before going to the dental college were unaware of the fact that the teeth may never be painful but are lost untimely due to periodontitis. In fact, there is no such thing as untimely loss. If you lose your permanent teeth before you die, that is untimely loss of teeth. Because, you need to eat until the day you die. And, When you lose your teeth earlier, your choices of food change, your amount of food changes and your speech becomes less understandable and children and youngsters hate being around with you because of the foul odor emanating from your oral cavity. Let's discuss some symptoms other than dental pain that may be an indication of oral and dental disease for which you need to see a dentist for consultation.

1. Loosening of teeth

Loosening of teeth which used to be firm can be due to various reasons including trauma, periodontitis, trauma from occlusion, and any other underlying pathology. Whenever calculus deposits around teeth and harbors a lot of plaque and bacteria, the gums start receding and the teeth appear longer. The bony support to the teeth is also compromised as the height of alveolar bone also decreases. As a result teeth start to feel loose. But, this phenomenon is completely painless. You'll probably lose your teeth in next few years if you ignore these symptoms.

2. Bleeding of Gums while brushing

Bleeding of gums is the first clinical sign of gingivitis, which is a technical term for inflammation of the gums or gingiva. Whenever the oral hygiene is poor and plaque and calculus deposits develop, then the gums become reddish and enlarged, tend to bleed more easily. If not treated in time, gingivitis may progress to periodontitis and more unfavorable will be the prognosis of the teeth. 

3. Foul Breath

Foul breath is the most disgusting thing which could turn off your nearest ones and may affect your life emotionally and financially as well. How can you convince a potential customer for sale if he runs away from you from a two-meter distance? This could be due to a lot of disorders which may originate in any part of the Gastrointestinal tract up to the stomach and sometimes even due to nasal and sinus cavity problems. Whatever may be the cause, it can be diagnosed and symptoms could be minimized. Most of the cases are due to tongue coating and presence of deep pockets in the gingiva. Proper oral hygiene and Oral prophylaxis will help to promote overall oral health as well as this particular symptom.

Likewise, there are many problems other than dental pain such as pus discharge from the gums, painful ulcers on the tongue and corners of mouth, yellowish hue of teeth, blackening of teeth and many more. You need not wait till the toothache is intolerable for consulting a dentist. A simple cavity that could have been restored two months back might deteriorate into a deep pulpitis which requires a root canal treatment costing you more time, money and suffering. 

Why is the World Getting Busier and Noisier?

People these days have adopted a noisier, more violent and more partying lifestyle.  They expect every day to be a party day. And, that party too, must be with a deafening loud DJ music in which more than 5-6 notes are played at any instant. Overloaded music in very high volume, intense exercises and cardiovascular workout trainings, movie shows, dance Clubs and Restaurants, all are ruling the current world. Have you ever contemplated why is it happening so? Yes, in the days of past, there used to be fairs too, loudspeakers with music used to be played, but they were gentler and less disturbing to a calm soul observing it. An enlightened soul also cannot tolerate the upbeats and cacophony of the revelry these days, it is becoming extreme.

Well, that might be due to the rat race that is going on. People need to have good grades, get a good job and earn a lot of money before they are reputable in society. While trying to do so, everyone finds himself in the chasm of servitude, helplessness, and despair. Every second you are constantly reminded of what you are supposed to do and what you are not supposed to do. You need something that will distract you from the continuous unlimited pressure. Had it been a physical pressure, today's men would simply be flat pulps of broad broad plates. Thankfully it doesn't have any physical significance.

When you sit quietly in a silent room with your eyes closed, you cannot remain calm. However hard you try, your inner soul is fighting a war. To overcome this by turning off the internal conflict seems nearly impossible. Then, comes the role of temporary distractors, Clubs, Partying, Alcohol, Smoking, Prostitution and what not. You cannot calm the inner soul, you cannot hear the voice without being agitated yourself so that you try to keep your focus out of it, by turning the volume of the outside more higher and higher. But, that relief lasts only till the music is on, only till the battery lasts, only till the alcohol flowing through your nerves last. Then again you hear the noise, again you feel agitated. It takes a simple reflection into one's self to know and observe this fact. But, who dares to give it a try?

Next time when you go to the party, don't drink a single drink and observe each person at the party very well. See how they are calming themselves, imagine how would they feel tomorrow morning, in a crowded park or a bus, just remain quiet and observe people, hear their conversation and realise your inner soul's voice. Hear it and befriend it. Then from the next time, you don't need any high volume music, alcohol, smoke, or any other transient auxiliaries to keep you high, you'll get a natural high all the time.
