Bad Singaporean Eating Habits

Food courts probably started its existence in Singapore. In the early seventies, in the effort to clean up the Singapore river and the environment, it was noted that hawkers plying the streets was a big source of littering and hence contribute to the pollution of the drains leading to rivers becoming an open sewer. Thus food courts were set up to house hawkers. This enabled the authorities to control not only the cleaniless but also the associated pests such as rats and cockcroaches. The indirect benefit was competition among the stalls led to very cheap eateries that benefited the man on the street. It was also very convenient for the population as all the local varieties of food can be found under one roof.
This transformation did not come easy. Many hawkers were reluctant to move into such a buildings as they felt that pushing their carts along the road or siting their carts at critical junctions gave them an advantage in gaining business. Thus there were many “illegal hawkers” who had to run when enforcements police came to catch them. Over time with continuous enforcement and also hawkers seeing the benefits not moving around food courts are part of our landscape. They are also a must standard feature in large shopping malls with diners eating in zircon comfort.

However Singaporeans may live in a first world country but their eating habits are still very third world.  Singaporeans are very fond of eating but when they eat at food courts their habits don’t differ much from pigs. They mess up the tables with their left over, don’t bother to clean up and just walk away from the mess. Fortunately we have cleaners to come and collect the empty plates and dishes. With increasing labour cost, these have become a big problem. To a foreigner setting foot into a  food court seeing all those rubbish pile on the tables, one must thought they have entered a pig sty.

Look at the mess
see i can finish my meal on my tray without messing up the table
the tray return trolley but look how full it is. Shows that a lot of people follow the campaign but  food centre workers don't know what to do.

see how neat it can be


Many years ago when you enter a food court the hawker assistant will come and take your order. They will also deliver the food to you and collect payment. This ended when labour cost underwent the first round of increase. So one must now queue for his food and bring to his own table. So if one can do that why can’t one return the plates to the stalls?  This is the difficult part.

Recently the government has started a drive to encourage patrons of food courts to return their trays at least to the tray return station. Some patrons have cooperated but sadly many have not done so, thus the tables are still a very unsightly scene.

One of my golf kaki suggested a monetary system to incentivise the population. He uses the example of the supermarket trolley. When you return the trolley, you can get back the dollar coin. If you don’t then someone else can return it for you to claim this dollar coin. So if the hawker charges one dollar more for the tray, then this encourages the diners to return the tray for a refund.


this is the trolley return station there is a coin lock on the top part of the trolley


Others suggest as Singapore is a “fine country” where fines are impose for littering, spitting etc, the government should also impose a fine on those who does not return the trays or clean up after eating. Fines have worked very well and if they still litter the table, then the authorities can make them clean up the food court. Ha ha, this sounds a bit drastic but it seems we locals are used to this sense of punishment

. More than ten years ago, I was at cafeteria in a Swiss supermarket having lunch with my family. After eating as we were about to leave the service lady came running to us and pointed to the tray return place. She also asked us to wipe the table. On a more recent note, I was in a food court in a Chiengmai shopping center, all the patrons clean up and return their trays.
So how come we Singaporeans have this bad habit of not cleaning up after eating and returning the trays?.

Pain Free keyhole Surgical Removal Of Wisdom Tooth

Pain Free Keyhole removal of Wisdom Teeth.
Dr Seow Onn Choong

Last week a young lady walked into my clinic. Both sides of her face was swollen. She was obviously in a lot of pain. She was crying when she told me she had surgical removal of her wisdom teeth just 4 days ago.
Her left face was really swollen with an obvious haematoma. She told me that she had been not eating properly since she could not open her mouth and asked me to be very gentle. I reassured her that i will be very gentle as I have managed many of such conditions before.
On examination it was obvious the surgeon had made very large incisions to remove the wisdom teeth. To make matters worse there were many ulcers on her lips and her cheek. This is an indication the surgeon was very rough in handling the procedure.
As can be seen on photo lots of ulcers.




Why is there  a need to remove wisdom teeth.
The majority of people are born with the curse of the Wisdom tooth. There are usually 4 wisdom teeth in the mouth and they are the last molars to erupt right at the back of the mouth. There is a lot of variation in the numbers. Very few people are lucky not to have any wisdom teeth. Some have anything from 1 to 3 but 4 wisdom teeth is definitely the most common.
Not all wisdom teeth give rise to problems. Those who give problems are always associated with lack of space for proper eruption and thus the teeth are stuck. This is known as impacted wisdom teeth. Food gets stuck in the gap causing not only frequent swelling of the gums but also cavities. The most damaging consequence is when the tooth in front gets a bad decay resulting lots of work to save it. More often than not root canal treatment is required but the results may not be good and the tooth is eventually extracted.

Types of impaction.
Gum impaction.
These teeth are usually partially or fully blocked by the gums. Their removal is usually easy.
Bony impaction.
In this situation the tooth maybe partially or fully covered by bone. Those teeth that is lying horizontally poses the most difficulty as a gum flap is usually necessary followed by bone removal.

What is the possible reason why wisdom teeth cannot erupt normally?
Nobody really knows why the wisdom cannot erupt out normally. Maybe is an evolutionary problem. Why do I come to this conclusion?
The wisdom tooth usually erupts only after 18 years old. If one looks at history, dentistry as a profession did not exist about 100 years ago. So dental care was absent, not even tooth brushing. Dental decay was very common and most people would have lost some teeth before they reach adulthood. This is especially so for the first molars that erupt out when one is 6 years of age. Thus by the age of 18 the first molars would have broken down. Since the wisdom tooth comes out then, it can restore back the bite. Thus the last molar is known as the wisdom tooth because it comes out at the age when one is wise enough.
In the modern world this seems ludicrous. However if you know that more than 100 years ago the  life expectancy of most people were no more than 45 years you would be able to appreciate the importance of 4 more teeth.

My learning curve in pain free wisdom tooth removal.
Most dental students perform only a handful of cases during their student days. Even these few cases are selected ones so that no problem arises. As a young dentist I had my fair share of  my problems especially when along time is required. This usually ends up with a lot of trauma and unnecessary pain.
I found it extremely stressful and unrewarding in the struggle during the surgery. Thus I approached what was then the most famous oral surgeon in Singapore to teach me the art. He was known as the King Dentist because he drives a Rolls Royce then. He was very kind. He wanted me to spend some time assisting him so that I can see and learn. It proved to be a most invaluable lesson and since then i have little difficulty in the surgical procedure. Later I experimented further with different instruments and techniques so much so i can achieve literally pain and swelling free removal.

Pain Free Experiences.
My own daughter’s experience is a good example. On her second time of removal she was dressed up for sports. I asked her what she planned to do. She said she was going to play football after the operation. Wow I asked? She said after the last operation she rested at home and she was bored cos nothing happened. So this time she is very confident nothing will come about.

Another friend’s son came on Christmas eve. He was a university student. He was taking advantage of the long Christmas break. His story is worth listening. He had a dental student friend who persuaded him to be a demo patient by an oral surgery professor. To him it was a big mistake cos he said he suffered a lot during and after the operation.
That evening i sms his dad. The reply was “He is eating like a pig, absolutely no pain and he does not even feel that he had a wisdom tooth operation” How wonderful to hear such news.

Last year my ophthalmologist friend’s son was going to UK to study medicine. He needed a second wisdom to be removed. I had removed his one side and now it was the next side. She was so impressed by the first time she told me to document it and present it to my profession. I told her I doubt the profession will believe me cos i am just a gp dentist without the titles.

This is the latest feedback from one happy person
Hi Doctor Seow,

sorry this is so late, been rather busy. Anyway here's my experience on my operation.
It is my first time plucking out my wisdom tooth, i heard of many experiences where, people have to stay at home for 1 week because it is very painful, some of my friends, cant even take solid food, they just want to sleep the pain away. During the second day of work, my friend asked, "wow you pluck out your wisdom tooth and still able to eat?" and another friend asked my during supper asked "are you sure you can eat?" I told them, "i felt no pain after the operation." I believe they were surprised


Anyway do look at the pictures and see for yourself.

The ideal age group to remove your wisdom tooth.

The wisdom tooth usually erupts at around 19 years old. This is also the best time to remove them. At this age the roots have not fully formed and thus not hardened. The bone socket they are in is still soft. This is to allow the roots to grow fully.  These are important factors that contribute to the easy  removal with much less risk of root fractures or damage to the inferior dental nerve.
As the site has not been affected by chronic infection or accumulation of bacteria colonies, healing is usually very swift and good. Infection usually cause further pain.. Without infections, antibiotics are not necessary at all.
A lot of people refuse to remove their wisdom tooth at this age usually due to ignorance. As a result with chronic food trap and inability to clean the site the neighbouring tooth develops a deep decay. By the time pain shows up the decay has affected the nerves.This  tooth needs root canal treatment followed by a crown. This is a troublesome and costly problem. As this is a difficult tooth to perform root canal treatment, most cases end up in failure and have to be extracted. All these suffering could have been prevented if the wisdom tooth is removed early.
