When children's permanent teeth come in substantially later than average, it is called delayed tooth eruption. In Factors Influencing Permanent Teeth Eruption, Ruta Almonaitiene, et al. argue that delayed tooth eruption does not normally indicate a medical problem.

When you factor in the residual values the vinyl fence will cost you about $168.00 per year while the western red cedar picket fence will cost you about $534.00 a year.
The true cost of a wood picket fence will be the initial cost plus all the staining for 10 years less the 10% residual value. Compare that cost to the cost of an aluminum fence with the same parameters, initial costs plus maintenance (zero maintenance costs for 10 years) less an impressive 65% residual value.ubtracting out the resale from original you end up with a TRUE COST of ONLY $1,732.50 for 10 years of aluminum fencing! Natural Wood Fencing with an initial cost of $3,600 plus first year staining brings it up $750 to $4,350.
