When should one brush the teeth?

In the surgery on a regular basis, dentists are faced with some very recurring questions, this can be likened with getting rid of the recurring decimal (Ten divided by three will mathematically give the result 3.3333333……………..
A few examples of such questions are what toothpaste is best for cleaning the teeth? What toothbrush is recommended for use to clean the teeth? How often should we clean our teeth?
The foregoing leads us to our topic today. The billion naira question since everything seems to be denominated in billions these days. Just how many times or when should one brush the teeth?
The use of toothbrush and a tooth-paste to clean the teeth is actually a routine, like most routines, there are individual variations. The extremes could be seen from individual to individual from those that do not have the time or could not afford to brush the teeth in days to those that will brush the teeth at every opportunity or after meals.
These variations are individual in nature and fit in individual lives.
The position on the issue amongst dentists also varies, from the traditional to the new thinking. The common selling point generally thought is that dentists recommend the use of a routine of brushing the teeth to remove dental plaque with a toothbrush and a fluoride containing toothpaste. Fluoride containing toothpastes are however not recommended in areas that by nature have a higher concentration of fluoride ion in the drinking water in which case non fluoride toothpaste may suffice. High fluoride concentration may be found in spring water sources, and most especially in places like in the north east of Nigeria. The water corporation where functional, should be in the best position to advice on the mineral and ionic content of water in their jurisdiction. (Hopefully these records are available at the water board).
The age long advice from dentist has been to have the teeth brushed first thing in the morning and last thing at night before going to bed.
This sounds logical and sensible as the teeth are actually are in danger of serious build up of plaque, just hypothetically let’s say one has not cleaned/brushed the teeth and mouth all day, eaten all day, failed to brush the teeth and mouth at night. Food debris will sit in the mouth and plaque easily accumulates on the teeth. Saliva flow is in addition very low in the night; the amount of saliva produced is at the lowest in the night. Saliva is a natural neutralizer of the acid produced by the bacteria in the mouth acting on the food debris to produce lactic acid which dissolves the tooth substance, the whole process initiating tooth decay. Saliva has a basic pH, which is the hydrogen ion concentration in a fluid. It is a measure, where substances are graded according to their acidity or basic nature, 1 being highly acidic and 14 being highly basic 7 is neutral so the saliva has a ph close to 7.4.
This factor makes the teeth most susceptible to the effect of acid at the period if plaque is not removed before bedtime.
Brushing after breakfast is sensible for those who will be at work and school or workshop whichever place of business.  Brushing first thing in the morning, not only freshens the breath, but also removes the halitosis (bad breath) common on waking in the morning. This has the additional advantage of stimulating the saliva production which neutralizes whatever acid has been produced in the night by the action of bacteria which are normal in the mouth, normal inhabitants that are. Chewing stimulates production of saliva. It is the opinion of some professionals, that is another school of thought posits that where it is possible to brush the teeth after meals, provision for a travel or pocket toothbrush can be kept in the office or in the school or work place , others advocate rinsing the mouth  with fluoridated mouthwashes, whilst others feel where it is not entirely possible the use of sugar free chewing gum containing xylitol will be able to cleanse the teeth stimulate saliva flo
